Rick Curtis updated OPENJPA-2330:
---------------------------------
Attachment: openjpa-2330.jar
Please try to test fix that I've attached here. This fix is based off trunk,
and it should work on 2.2.x, but let me know if it doesn't work. You can either
lay this class on top of your existing openjpa jar, or you can preprend it to
your classpath. Let me know how it goes.
Your other option is to pull the patch out of the jar, and build your own fix
based off your version of OpenJPA.
