Rick Curtis updated OPENJPA-2493:
---------------------------------
Attachment: OPENJPA-2493.ut.patch
> SQLException while processing a query result
> --------------------------------------------
>
> Key: OPENJPA-2493
> URL: https://issues.apache.org/jira/browse/OPENJPA-2493
> Project: OpenJPA
> Issue Type: Bug
> Components: kernel, query
> Affects Versions: 2.2.2, 2.3.0
> Reporter: Rick Curtis
> Attachments: OPENJPA-2493.ut.patch
>
>
> I encountered a bug in a test environment that I wanted to open so I don't
> forget about it.
> My best guess is that this bug is somewhere in one of the query / sql caches.
> It looks very similar to OPENJPA-2482, but it is indeed different. Attached
> below is a multithreaded test that is able to recreate the stacktrace below
> 75% of the time.
