Subject [jira] [Commented] (OPENJPA-2330) Stackoverflow due to endless recursive calls
Date Fri, 15 Feb 2013 21:39:13 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-2330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13579524#comment-13579524
] 

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

> We wish to report another bug that generates a memory overflow resulting in an infinite
recursive loop. Here are two stacktraces apparently from the same bug:
