Kristian Waagan commented on DERBY-3607:
----------------------------------------
Okay.
I see that you are using c3p0, I assume it is for connection pooling?
Can you try to disable it?
We know there are some problems using it with Derby, because it may interrupt
threads. I'm not sure if that is still the case for the newest version of c3p0.
Another option is to use the client driver instead of the embedded driver, and
see if you still get the corruption.
