* jode/decompiler/MethodAnalyzer.java.in (skipWriting): Don't skip
empty constructor that have a throws clause.

in config.status.
* jode/expr/Expression.java.in (makeInitializer): Now takes the
type of the initialization. Changed all callers.
* jode/expr/ConstantArrayOperator.java (makeInitializer): Check
that type is our array type, otherwise we can't omit new Array[].
* jode/decompiler/LocalInfo.java (markFinal): Don't check that
only one write is present. If two writes are in an then and an
else branch of an if, the local can still be final.

types correctly: byte[] is something completely different than
int[].
(getSuperType): Likewise.
* jode/expr/FieldOperator.java.in (getFieldInfo): New function.
(needsCast): A cast is also needed if the field is private or
package scope and the current type can't access the field.

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.
