Frank-

This sounds like something that was fixed in the trunk for revision  
#584463:

  <http://svn.apache.org/viewvc?view=rev&revision=584463>

It was a fix for a problem introduced by <https://issues.apache.org/jira/browse/OPENJPA-378

 >.

The latest trunk snapshots don't have the bug, but the fix would need  
to be backported to 1.0 branch if a fix is needed for that line.

Can you open a JIRA so we can track it?
