Mike, I think I have an openJPA test case for this issue. I will update the JIRA with openJPA specific test case , as soon as I find it.

I wouldn't have been sure it applied to OpenJPA. Do either of you have a testcase that reproduces the issue without JDO? -mike On Wed, May 27, 2009 at 8:13 AM, Ravi Palacherla <[email protected] > wrote: > Sorry, I do not have a proper resolution for this. > > The following JIRA was already opened for this: > http://issues.apache.org/jira/browse/OPENJPA-453 > > It is currently unassigned. > > I think the cause of the issue is, if you have multithreaded environment > and when transactions begin and end, all > references to embedded objects become invalid.
