GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>

Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:

Renamed back from removeBadJSR (see patch from 2001-02-04). The
checkAndRemove* functions mustn't change the successors while they
iterate over them. Instead of removing good jsr they mark them as
good and removeJSR will finally remove them.
(checkAndRemoveJSR): See above.

-e is not supported on all architectures (Solaris) and -f is more

allow parenthesis around left hand side, so use NO_PAREN and don't
call lhs.dumpExpression() with priority.

* jode/expr/IIncOperator.java (dumpExpression): likewise.
* jode/flow/TransformConstructors.java (jikesAnonInner): Removed,
since it wasn't used: This information is stored in OuterValues
now.
* jode/decompiler/LocalInfo.java (isConstant): Always return true
so that inner classes that access final locals work, even if we
can't decide that the local can be final.
2001-02-05 Jochen Hoenicke <jochen@gnu.org>
* jode/expr/InvokeOperator.java.in (Environment.invokeMethod):
Fixed the call to ClassInfo.forName: it expects a class name, while
ref.getClazz() gives a type signature.

successors left.

(skipFinExitChain): New function.
(removeJSR): Replaced by ...
(removeBadJSR): ... this.
(checkAndRemoveJSR): Use the new functions. Much simpler and
handles nested synchronized blocks. It now traces the whole JSR
and monitorexit chain before a jump to the first entry via
skipFinExitChain, then checks and remove the first JSR
resp. monitorexit. JSR jumps are simply ignored now.
(checkAndRemoveMonitorExit): likewise.
* jode/flow/StructuredBlock.java.in (prependBlock): New function.
* jode/flow/CatchBlock.java.in (makeDeclaration): Generate name
of dummyLocal, since nobody else will generate it.
2001-02-03 Jochen Hoenicke <jochen@gnu.org>
* jode/bytecode/BytecodeInfo.java.in (read): Remove bogus
exceptionHandlers, whose catchers just throw the exception again.
This kind of entries are inserted by an obfuscator and would break
JODE.
* jode/util/UnifyHash.java.in (iterateHashCode): Call cleanUp,
to clean unneeded references.
* jode/flow/TransformConstructors.java (transformOneField):
Changed to private. Take field number as parameter. Check that
expression doesn't contain a FieldOperator for a later field of
the same class or a PutFieldOperator. Changed all callers.
2001-02-01 Jochen Hoenicke <jochen@gnu.org>
* jode/jvm/CodeVerifier.java.in (Type.mergeType): If array elem
types can't be merged, return tObject as common super type.
* jode/type/ArrayType.java (getGeneralizedType): If array elem
type can't be intersected, return tObject as common super type.
* jode/flow/TransformExceptionHandlers.java.in: Merged patch from
the 1.2 tree to support javac 1.3 synchronized blocks. Doesn't
handle nested synchronized blocks yet.
* jode/expr/Expression.java.in (dumpExpression): Show runtime
exception when it occurs.
2001-01-31 Jochen Hoenicke <jochen@gnu.org>
* jode/expr/Expression.java.in (updateParentTypes): Call setType,
instead of merging the types. Other childs want to know about the
type change as well.
* jode/decompiler/LocalInfo.java (combineWith): Reorganized a bit,
but no changes.
* jode/expr/InvokeOperator.java.in (dumpExpression): Always print
the ThisOperator if a field is from a parent class of an outer
class is used. And always qualify the this operator if not
innermost.
2001-01-30 Jochen Hoenicke <jochen@gnu.org>
* jode/jvm/SyntheticAnalyzer.java.in (checkConstructorAccess):
Allow the special unifyParam to be the last parameter.
2001-01-30 Jochen Hoenicke <jochen@gnu.org>
* jode/decompiler/TabbedPrintWriter.java: Better gnu style handling:
(openBraceClass) (closeBraceClass)
(openBraceNoIndent) (closeBraceNoIndent): new functions.
(closeBraceNoSpace): Removed.
* jode/decompiler/Options.java (GNU_SPACING): new constant.
(GNU_STYLE): changed to include GNU_SPACING.
* jode/decompiler/ClassAnalyzer.java.in (dumpSource): Use
open/closeBraceClass.
* jode/decompiler/MethodAnalyzer.java.in (dumpSource): Use
open/closeBraceNoIndent. Insert a space for GNU_SPACING.
* jode/decompiler/InvokeOperator.java.in (dumpExpression): Insert
a space for GNU_SPACING, use open/closeBraceClass for inner
classes.
* jode/decompiler/UnaryOperator.java (dumpExpression): Insert
a space for GNU_SPACING.
2001-01-30 Jochen Hoenicke <jochen@gnu.org>
Added pascal style from Rolf Howarth <rolf@squarebox.co.uk>
* jode/decompiler/Options.java (PASCAL_STYLE): new constant.
(BRACE_FLUSH_LEFT): dito.
* jode/decompiler/Decompiler.java (setOption): detect pascal option.
* jode/decompiler/Main.java (main): dito.
* jode/decompiler/TabbedPrintWriter.java (openBrace,
openBraceContinue, closeBrace, closeBraceNoSpace,
closeBraceContinue): handle flush left.
2001-01-30 Jochen Hoenicke <jochen@gnu.org>
* jode/type/NullType.java (intersection): Removed, since the
version in ReferenceType is more correct. Before
tNull.isOfType(tRange(X,tNull)) returned false, which lead to
incorrect behaviour in InvokeOperator.needsCast.
* jode/decompiler/FieldAnalyzer.java.in (dumpSource): Removed the
"= null" hack for final fields; it was not correct, since the
field could be initialized in a constructor.
* jode/decompiler/TabbedPrintWriter.java (BreakPoint.endOp):
Simplified the code, copy options always from child.
* jode/jvm/SyntheticAnalyzer.java.in (unifyParam): new field.
(checkConstructorAccess): Allow the special Parameter, whose
purpose is to distinguish the wrapper from the real constructor
and give him a "$" in the type signature, to appear at every
position. It doesn't appear at position 1 for inner classes.
Store the position in unifyParam.
* jode/expr/InvokeOperator.java (isGetClass): Allow the method to
be declared inside an outer class: We simply check if we can get
the method analyzer.
(simplify): handle unifyParam.
* jode/expr/PopOperator.java (getBreakPenalty): return penalty of
inner expression. (dumpExpression): Call dumpExpression of
subexpression immediately without priority.

HISTORY:
Someday I found guavad, a disassembler for java byte code (it does
similar things like `javap -c'). I used it on a class file, and found
that it was possible to reconstruct the original java code. First I
did it by hand on some small routines, but I soon realized that it was
a rather stupid task, and that I could write a perl script, that does
the same. At the end of the next day I had the first working
decompiler.
Now while it was working, it was not easy to use. You had to
decompile the code first with a disassembler, cut the method, you
wanted to decompile and then run the perl script on it. So I decided
to get some information of the class files and do this all
automatically. I decided to write it in java now, because it suited
best.

<h1>Blue Sky</h1>
<p>This section contains features that I think would be great to have,
but are also very hard to implement. The name of the section is
inspired, by <a
href="http://www.mozilla.org/blue-sky/">Mozilla</a>.</p>
<p>Currently this are all my own ideas. But if you send me an idea
for an interesting feature, I will add it to this list.</p>
<h2><i>Out</i>line inlined methods</h2>
<p>If java gets called with `<code>-O</code>' switch, it inlines methods,
that are private, final, or static and contain no loops. When
decompiling this it sometimes produces really ugly code. The right
way to solve this would be to <i>out</i>line the code again. This is
possible but requires to find the inlined method. </p>
<p>The name `outline' was suggested by <a
href="http://www.informatik.uni-oldenburg.de/~mw">Michael</a>.
</p>
<h2>Better names of local variables</h2>
<p>The local variable naming is very stupid. Even with pretty it just
names the variable after the type with a unifying number appended. A
method containing very much objects of the same type looks very
ugly. </p>
<p>My plan is looking at the assignments. If we have locals in
assignments
<pre>
int l_1 = array.length
String l_2 = object.getName()
</pre>
we could name them "length" and "name". If we
have assignments:
<pre>
MenuItem local_1 = new MenuItem("Open");
MenuItem local_2 = new MenuItem("Save");
</pre>
good names would be <code>miOpen</code> and <code>miSave</code>. </p>
<p>It is currently possible to assign a <i>(hint name,type)</i> pair
to a local. If the type matches, the local will be named after
<i>hint name</i>. This could be extended by giving them several
weighted hints and constructing the name in an intelligent way. </p>
<h2>Better deobfuscation features</h2>
<p>First there should be a good Renamer: Methods that simply
return a field value should be renamed to get<i>FieldName</i>.
Fields should be named after their type, maybe also by assignments
(see section about local variable names).</p>
<p>The deobfuscator should detect inner and anonymous variables,
synthetic methods and so on, and rename them accordingly.</p>
<h2>Handling of Class.forName in obfuscator</h2>
<p>The obfuscator should detect Class.forName constructs (and
similarly for methods and fields) and if their parameters are constant
it should change the parameter according to the rename function. </p>
<h2>Merging javadoc comments</h2>
<p>It would be nice if the decompiler could merge the javadoc comments
into the class file. More and more people use javadoc to comment the
public api of their java classes. It shouldn't be too difficult to
copy them back into the java code. </p>
<p>This doesn't need to be built into the decompiler. A script that takes
the javadoc pages and the decompiled code can easily merge them.</p>

<h1>FAQ - Frequently Asked Questions</h1>
This is a list of some questions that pop up from time to time.
<h2>Decompiler issues</h2>
<h3>The decompiler crashes with a VerifyException, what can I do?</h3>
<p>The class isn't verifiable, probably because there is not enough
information about used classes. See the question about the
classpath.</p>
<p>This could also be caused by malicious bytecode, or because there
is a bug in Jode's verifier.</p>
<h3>What should be included in the classpath?</h3>
<p>Jode needs to know the full class hierarchie to guess the types.
This includes not only the classes in the program, but also the
libraries used by the java program, even the Java runtime library.
You should set the classpath to include all these classes.</p>
<p>If you don't specify the classpath on the command line, Jode uses
the same as your Java Virtual Machine.</p>
<p>As last resort, if Jode can't find a class in the classpath it uses
reflection to ask the Virtual Machine. This works quite well, but
loading classes can have side effects, e.g. when AWT classes are
loaded, an AWT thread is created, even though Jode doesn't need
it.</p>
<h3>Why doesn't Jode decompile my inner class
<code>MyClass$Inner.class</code>?</h3>
<p>You should decompile the outermost class (<code>MyClass</code> in
this case). The produced code contains the inner class. </p>
<h2>Obfuscator issues</h2>
<h3>What should be included in the classpath?</h3>
<p>The program, all libraries, the Java runtime library. Don't omit a
library even when you don't want to obfuscate it.</p>
<h3>What should I preserve</h3>
<p>The most common mistake is to preserve a class. In most cases this
is not what you want. This only makes sure the class won't be
renamed, it doesn't prevent it from being stripped. Instead you
should preserve methods and constructors. The constructor is just a
method with the special name <tt>&lt;init&rt;</tt>. </p>
<p> Another common mistake is to omit the type
signature, e.g. to preserve <tt>Class.main</tt> instead of
<tt>Class.main.([Ljava/lang/String;)V</tt>. That doesn't work. If
you don't want to care about the format of the type signature use a
wildcard as in <tt>Class.main.*</tt>. </p>
<h3>What is a type signature</h3>
<p>The type signature is a machine readable representation of a java
type that is used all over in java bytecode. The JDK ships a command
named <tt>javap</tt>. With <tt>java -s</tt> you can lists the fields
and methods of a class with their type signatures.</p>
<p> If you are interested in the format of type signatures read the
Java Virtual Machine Specification, Chapter 4.3 Descriptors</p>

<h2>History</h2>
<p>Someday I found <code>guavad</code>, a disassembler for java byte
code (it does similar things like <code>javap&nbsp;-c</code>). I used
it on a class file, and found that it was possible to reconstruct the
original java code. First I did it by hand on some small routines,
but I soon realized that it was a rather stupid task. So I wrote a
small <a href="dasm_to_java.perl"><code>perl</code> script</a> that
did this process automatically. At the end of the next day I had my
first working decompiler.</p>
<p>Now while the <code>perl</code> script is working, it is not easy
to use. You have to decompile the code first with a disassembler, cut
out the code of a single method, and run the perl script on it. I
decided to get the bytecode directly out of the class files and do
this all automatically. I decided to write it in <code>java</code>
now, because it suited best.</p>
<p>Just for the records: the java code is now more than 50 times
bigger than the original perl script and is still growing.</p>

<P><i>JODE</i> is a java package containing a decompiler and an
optimizer for java. This package is freely available under the GPL
(see <a href="./license.html">license</a>).<p>
<P>The decompiler takes <tt>class</tt> files as input and produces
something similar to the original <tt>java</tt> file. Of course this
can't be perfect: There is no way to produce the comments or the names
of local variables (except when compiled with debuging) and there are
often more ways to write the same thing. But <i>JODE</i> does its job
quite well, so you should give it a try: <a href="./applet.html">start
the applet</a>.</P>
<P>The optimizer transforms <tt>class</tt> files in various ways with
can be controlled by a script file. It supports the following
operations:</p>
<ul>
<li>Renaming class, method, field and local names to shorter,
obfuscated, or unique names or according to a given translation
table</li>
<li>Removing debugging information</li>
<li>Removing dead code (classes, fields, methods) and constant
fields</li>
<li>Optimizing local variable allocation</li>
</ul>
<h2>News</h2>
<ul>
<li><i>JODE</i> is now hosted by <a href="http://sourceforge.net/">SourceForge</a>.</li>
<li>The latest <a href="http://sourceforge.net/cvs/?group_id=3790">CVS</a> version breaks long lines</li>
<li>I can now decompile <b>inner and anonymous</b> classes.</li>
<li>The optimizer (aka obfuscator) can be customized via a small
config file</li>
<li>Jode is <tt>autoconf</tt>igured.</li>
</ul>
<h2>Limitations</h2>
<p>If not all dependent classes can be found, the verifier (which is
run before decompilation starts) may exit with a type error. You
can decompile it with <tt>--verify=off</tt>, but take the warning
serious, that types may be incorrect. There's sometimes no way to
guess the right type, if you don't have access the full class
hierarchie.<br>
This is not a bug in the verifier: java will complain the same way,
if it is run with bytecode verification turned on. And if you don't
have the dependent classes, you can't compile the code again.</p>
<p>There may be situations, where the code doesn't understand complex
expressions. In this case many ugly temporary variables are used, but
the code should still be compileable. This does especially happen
when you compile with <tt>`-O'</tt> flag and javac has inlined some
methods. </p>
<p>Sometimes this program may exit with an <code>Exception</code> or
produce incorrect code. Most time the code can't be compiled, so that
it can be easily spotted. If you have one of these problems (except
those that occur on some of the <code>jode.test</code> files, I would
be very interested in a bug report (including the <code>class</code>
file, if possible). </p>
<p>Sometimes <i>JODE</i> generates some GOTO expression and labels.
This shouldn't happen any more with code produced by javac or jikes.
But some flow obfuscator may provoke this. In that case you can run
the Obfuscator first (to optimize away the flow obfuscation ;-).</p>

<h1>Using the Decompiler</h1></a>
After you have <a href="./download.html">downloaded</a> the necessary
packages, put them into your <tt>CLASSPATH</tt>:
<ul><li>Under Windows you have to start a MSDOS session and type
something like:
<pre>
set CLASSPATH=C:\download\jode-xxx.jar;C:\swing\swingall.jar
</pre>
</li><li>Under Unix you start a shell and type (for bourne shell):
<pre>export CLASSPATH=/tmp/jode-xxx.jar:/usr/local/swing/swingall.jar</pre>
or for csh:
<pre>setenv CLASSPATH /tmp/jode-xxx.jar:/usr/local/swing/swingall.jar</pre>
</ul>
<br>
There is also a batch file for windows and a script file for unix,
that you can use. Adapt the CLASSPATH in the file and put it to a
convenient location.
<pre>
jar -xvf jode-xxx.jar bin/jode.bat <i>resp.</i> bin/jode
</pre>
<a name="cmdline"><h3>Command Line Interface</h3></a>
The most powerful way to start <I>JODE</I>'s decompiler is the command
line interface. Some people don't like long command lines; they
should go to the next section. <br>
Start the class <tt>jode.decompiler.Main</tt> with the options. The
following command will give a complete list of the available commands:
<pre>java jode.decompiler.Main --help</pre>
<a name="awt"><h3>AWT Interface</h3></a>
The AWT Interface looks exactly like the <a href="./applet.html">applet</a>. In fact the applet uses the AWT Interface. You start it
after setting the <tt>CLASSPATH</tt> (see <a href="./usage.html#decompiler">above</a>), with
<pre>java jode.decompiler.Window</pre>
In the classpath line you can enter a number of jar files, zip files
and directories separated by comma(<tt>,</tt>). Then enter the
dot(<tt>.</tt>) separated name of the class you want to decompile.
Press the <code>start</code> button and the decompiled class should
appear. You can save it via the <code>save</code> button.
<a name="swing"><h3>Swing Interface</h3></a>
For the swing interface you need java version 1.2 or the separately
available swing package (see <a href="./links.html#swing">link
page</a>. You can invoke it like this:
<pre>
java jode.swingui.Main --classpath classes.jar
</pre>
The swing interface will show the package hierarchie of all classes
in the classpath on the left side. You can now select a class and the
decompiled code will appear on the right side. Via the menu, you may
change the classpath or switch between package hierarchie tree and
class inheritence tree.<br>
The swing interface is very useful to browse through class files if
you don't have the source code. You can also use it to trace bugs in
library code. It is not meant to generate <tt>java</tt> files and so
you won't find a save option there.<br>
<a name="java"><h3>Java Interface</h3></a>
If you want to integrate <i>JODE</i> into your own java program, you
can use the <a
href="Decompiler.java"><code>jode.decompiler.Decompiler</code></a>
class. Note that the GPL only allows you to integrate <i>JODE</i>
into GPL programs. Please contact me if you use <i>JODE</i> in this
way.<br>
You may use this <a
href="ftp://jode.sourceforge.net/pub/jode/jode-embedded.jar">stripped
down jar archive</a> containing all necessary classes.
<a name="optimizer"><h1>Using the Obfuscator</h1>
To use the obfuscator you should first create a script file, say <a
href="myproject.jos"><tt>myproject.jos</tt></a>. Then you can invoke the
obfuscator with:
<pre>
java jode.obfuscator.Main myproject.jos
</pre>
<p>The script file should contain the following options: </p>
<p>First select the classpath. You should include everything in the
classpath that you need to run your application. This also includes
the system class files (Sun puts them into <code>classes.zip</code> or
<code>rt.jar</code>))</p>
<pre>
classpath = "c:\\jdk1.2\\jre\\lib\\rt.jar","d:\\project\\java",
"ftp://www.myorg.org/pub/classlib.jar"
</pre>
<p>Specify where you want the obfuscated classes to go. I recommend
to write them directly into a zip file, but you can also give a
directory.</p>
<pre>
dest = "obfuscated.zip"
</pre>
<p>You can make <i>JODE</i> write its translation table. This table
can be used later to undo the name obfuscation, or you can look there
to decrypt exceptions you may get.</p>
<pre>
revtable = "translat.tbl"
</pre>
<p>Select what you want to strip. There are several
possibilities, which can be separated by comma(<tt>,</tt>):</p>
<dl>
<dt>unreach</dt>
<dd>strip unreachable methods and classes.</dd>
<dt>source</dt>
<dd>remove the name of the java file (exceptions will get unreadable).</dd>
<dt>lnt</dt>
<dd>remove the line number table (exceptions will get unreadable).</dd>
<dt>lvt</dt>
<dd>remove the local variable table (debugging doesn't work).</dd>
<dt>inner</dt>
<dd>strip inner class info (reflection doesn't work correctly).</dd>
</dl>
<pre>
strip = "unreach","lvt","inner"
</pre>
<p>Select the packages and classes you want to obfuscate. You should
only include libraries, that you don't ship separately. If you give a
package, all classes and subpackages are loaded. You can also use
<code>*</code> as wild card, that matches everything (including dots).
</p>
<pre>
load = new WildCard { value = "org.myorg.myproject" },
new WildCard { value = "org.myorg.mylib*" },
new WildCard { value = "org.otherorg.shortlib" }
</pre>
<p>Select the methods and classes you want to preserve. This is
the <tt>main</tt> method for applications and the default constructor
<tt>&lt;init&gt;.()V</tt> for applets, resource bundles and other classes
that you load manually at runtime.<br> You have to give the method
name and the type signature to identify your method. <tt>javap
-s</tt> will show you the type signatures for your classes, but you
may also use <tt>*</tt>, to select all methods with that name.</p>
<pre>
preserve = new WildCard { value = "org.myorg.ApplicationClass.main.*" },
new WildCard { value = "org.myorg.AppletClass.&lt;init&gt;.()V" },
new WildCard { value = "org.resources.Bundle*.&lt;init&gt;.()V" },
</pre>
<p>If you want to obfuscate (or just shorten) the identifier you can
specify a renamer. There are currently following renamer
available</p>
<dl><dt>StrongRenamer</dt>
<dd>Renames to the shortest possible name. You can give a charset
that should be used. It uses the same name as much as possible.</dd>
<dt>UniqueRenamer</dt>
<dd>Renames to unique identifier of the form <tt>xxx123</tt>. Useful
to reduce name conflicts, before you decompile an obfuscated package.</dd>
<dt>NameSwapper</dt>
<dd>This renamer just swaps the names. This is a funny obfuscation
option that is not very strong, but very confusing.</dd>
<dt>KeywordRenamer</dt>
<dd>Renames identifiers to keyword. You can give your own list of
keywords as parameters. Resulting code is not decompilable directly,
<b>but it is <i>not</i> legal bytecode either</b>. Some paranoid
web browsers refuse to run applets containing keywords as identifiers
(and they are completely within the Java VM spec).</dd>
</dl>
<pre>
renamer = new StrongRenamer
</pre>
<p>You can also create a renaming table with the same format as the
table written by revtable. The entries in the table get precedence
over renamer. Entries not in the table will get renamed by the
renamer.<p>
<pre>
table = "translat.tbl"
</pre>
<p>Now you can select the analyzer. The purpose of the
analyzer is to mark all reachable methods, find out which methods
needs to get the same name (overloading), and which method names
mustn't change (overload of library methods, e.g. <tt>nextElement</tt>
for <tt>Enumeration</tt>s). There are currently two analyzers.
<dl><dt>SimpleAnalyzer</dt>
<dd>Straight forward analyzer. It is fast and will remove dead code
on method basis.</dd>
<dd><dt>ConstantAnalyzer</dt>
<dd>Strong analyzer that will determine, which fields and instructions
have constant values. It will remove dead code on instruction basis
and replace constant instruction with a load of the constant, or
remove them completely.<br> This analyzer is especially useful to
revert the flow obfuscation of some other obfuscators.</dd>
</dl>
</p>
<pre>
analyzer = new ConstantAnalyzer
</pre>
<p>Pre- and Post transformers transform the bytecode before
resp. after the Analyzer runs. Using this default should be okay.
You may remove the LocalOptimizer, though, if you have problems.</p>
<p>In the future I may add some new post transformers, that do string
encryption, flow obfuscation and similar things. If you want to write
your own Transformers please contact me, since the next version will
change the bytecode interface.</p>
<pre>
post = new LocalOptimizer, new RemovePopAnalyzer
</pre>
