Knut Anders Hatlen updated DERBY-3258:
--------------------------------------
Attachment: d3258.diff
I am able to reproduce this fairly quickly in my environment if I start five
threads running this test in a loop. Most of the time it's the assert on line
146 that fails, but sometimes it's the assert on line 140.
With the attached patch, which makes the test wait for the post commit thread
to complete before it queries the lock table, I'm not able to reproduce the
failure anymore.
