When i try to include jakarta commons lang in my classpath (no matter where), I get UnsupportedOperationException (dbcp is calling that user/password not-implemented overloaded version of getConnection or however it was called again :) )

I'm only using one hibernate configuration file, and the Exception doesn't occur when i remove commons lang from the classpath (but then, of course, the compiler complains :) )

I don't feel like getting close to a solution, and unfortunately I seem to be the first one on the internet to run into this (!), or at least google didn't reveal anything

As I already suspected, there was a reason why I was the only one - not a Commons lang related problem

Does anybody have some more in-depth information regarding why this error occurs? I thought I was long past it, and then it came back and struck suddenly, with no remorse and no transparent reason whatever
