+/**
+ * A [Transformer] responsible for removing two kinds of redundant exception
+ * handler.
+ *
+ * - [ZKM](http://www.zelix.com/klassmaster/)'s
+ *   [exception obfuscation](https://www.zelix.com/klassmaster/featuresExceptionObfuscation.html),
+ *   which inserts exception handlers that catch [RuntimeException]s and
+ *   immediately re-throw them. The exception handlers are inserted in
+ *   locations where there is no Java source code equivalent, confusing
+ *   decompilers.
+ *
+ * - Jagex inserts a try/catch block around every method that catches
+ *   [RuntimeException]s, wraps them with a custom [RuntimeException]
+ *   implementation and re-throws them. The wrapped exception's message
+ *   contains the values of the method's arguments. While this is for debugging
+ *   and not obfuscation, it is clearly automatically-generated and thus we
+ *   remove these exception handlers too.
