Reverted all my changes (deleted the files that were marked as modified in
svn stat and then ran svn update), did the whole:
ant
ant testing
ant buildjars

Tried the same test only to find the very same error after a couple of
hours. Could it somehow be that I'm running the tests with Java 1.4? I'm
gonna give it a try with 1.6 in the meanwhile anyway...

If anyone has an idea, please let me know.

I'll leave here some of my environment variables that might be useful:
