New Not always
Particularly not if it has been obfuscated by [link|http://www.preemptive.com/|these guys].

(Reference and description of their technique [link|http://www.pbs.org/cringely/pulpit/pulpit20020613.html|courtesy] of Cringely.)

Cheers,

New There's a big catch
Obfuscators change method names.

This means method name lookups fail when using dynamic invocation techniques (which I do a *lot* in non-trivial programming - its what makes OO development really powerful). So any code that works well with obfuscation is going to be 100% statically bound - you might as well write it in C or maybe C++ then.

Apple ported WebObjects and their OR Mapping framework to Java then released that. An hour of machine time later and I have the source code. If you look around the code a bit you find extensive use of dynamic invocation - obfuscation would break the code.

I think this is typical of the more powerful software.
