Rick Curtis commented on OPENJPA-2445:
--------------------------------------
It might be helpful if you also post the contents of your persistence.xml file.
Also, can you give us more details on when this happens? How frequently does it
happen? Is it just near application start up? Anything more than a stack trace
would be helpful.
Thanks,
Rick
