Gustavo Lopes commented on OPENJPA-2312:
----------------------------------------
I didn't explore further the possibility that the Spring configuration was the
problem because merely changing the data source from H2 to MySQL seemed to make
the issue go away. I'll take a closer look along the lines you suggested
tomorrow.
Thanks
