And the worst case is developers use third-party routines that they

this regard, although at least with open source you can go in and
find the issues, but that of course requires that you learn the
intricacies of the open source code, which defeats at least part of
the purpose of using third-party packages in the first place :).

Add to that the 3rd party packages that are poorly or totally not documented.

There have been a number of times when I get a NPE deep inside a 3rd party class with no explanation of why it's happening.

Often, when I encounter this situation, I end up decompiling the libraries so I can figure out what is happening (JAD is my best friend sometimes). I'm SURE I'm violating some licensing agreement when I do this, but if they don't want me to decompile the code, they should provide better documentation.
