Date Thu, 07 Feb 2013 11:05:12 GMT
Guillaume Chauvet created OPENJPA-2330:
------------------------------------------

             Summary: Stackoverflow due to endless recursive calls
                 Key: OPENJPA-2330
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2330
             Project: OpenJPA
          Issue Type: Bug
    Affects Versions: 2.2.1, 2.2.0
            Reporter: Guillaume Chauvet
            Priority: Critical


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:

First stacktrace sample :
