I keep getting this exception and was confused. Before every test unit I'm grabbing a new session, and at the end of every session I'm always doing a rollback. I do not commit to the database. I was wondering why I would be getting this exception if I'm doing a rollback.
I am running 3 tests back to back in the same jvm(batch mode) for speed, but have found myself getting a lot of these exceptions.
I was wondering how I should be handling this exception, or what I should be doing to prevent this exception?
Thanks,
