Kevin Sutter commented on OPENJPA-2330:
---------------------------------------
Hi,
Can you give some more details on your environment and the scenario that is
causing this failure? I can see where it looks like a potential issue with the
PersistenceUtils, but what was the user scenario that got you into this mess?
We have some tests (junit, functional, cts) that utilize the PersistenceUtils.
We would need some more information, preferably a junit, in order to recreate
the error. Thanks!
