Mark Struberg resolved OPENJPA-2672.
Resolution: Fixed
Assignee: Jody Grassel (was: Mark Struberg)
seems to have nothing to do with that. It seems to be the old story with the
multiple 'Entity1' tables which results in timing issues on fast computers.
Will merge over the changes I did on trunk to fix this problem.

Mark Struberg commented on OPENJPA-2672:
Not quite sure if it really has to do with this change, but since then our
build is broken on Linux.
https://builds.apache.org/job/OpenJPA-2.4.x/8/
It builds fine on OSX though. Will try to reproduce on my local Fedora
workstation.
