I haven't had a chance to look at the testcase in depth either. As it turns
out the symptom looks very similar to
OPENJPA-1424<https://issues.apache.org/jira/browse/OPENJPA-1424>-
which was fixed very recently.

Can you try using one of the latest OpenJPA 1.2.3 SNAPSHOT
builds<http://people.apache.org/repo/m2-snapshot-repository/org/apache/openjpa/apache-openjpa/1.2.3-SNAPSHOT/apache-openjpa-1.2.3-SNAPSHOT-binary.zip>outside
of WebSphere?
