Bryan Pendleton commented on DERBY-7147:
----------------------------------------
Uh-oh! Reverting your patch makes the problem go away.
I eyeballed your change but nothing jumped out at me.
But we're making progress!
Since I can reproduce a problem, I'll find some time over the long weekend to
try adding some debug information and see what I can learn.
