Rick Curtis commented on OPENJPA-2330:
--------------------------------------
I wasn't able to figure out the root problem yet, but it appears that it has
something to do with the interaction between OpenJPA and Apache BeanValidation.
If you're not using bv, a workaround for the meantime would be to set
<validation-mode> to NONE. Hopefully I'll get some more time next week to
continue digging into this issue.
Thanks,
Rick
