ProGuard Java Optimizer and Obfuscator

You can display the contents of class files with

proguard.bat -injars mycode.jar(mypackage/MyClass.class) -dontshrink -dontoptimize -dontobfuscate -dontpreverify -dump

I'm not familiar with JSF, but you should check that the necessary classes, methods, and annotations are the same in the original code and in the processed code.
