More on Obfuscators
The author of Proguard, in the true spirit of open source software development, has links to other alternative obfuscators/optimizers on his site. I have already seen some of them because they are also included in the list at mindprod. There are exceptions and jode is one of them.
Proguard as we have already seen is ahead of the rest. On first glance jode seems to be reasonably close in many aspects the difference though is in the documentation.
The last obfuscator that was looked at is JoGa. It has a nice graphical user interface and seemed to work well, but when processing a large project it encountered a stack overflow. This can probably be overcome by tweaking the JVM settings.
