Heath Thomann updated OPENJPA-2284:
-----------------------------------
Attachment: OPENJPA-2284-mvn-test.zip
I'm attaching my test to recreate this issue. This is a stand alone maven
test/project which can be imported into eclipse as an existing mvn
project.....sorry, have not have time to convert it to a test which can be
applied to OpenJPA.....the 'Simple.java' entity and orm.xml are the two
pertinent pieces.....
Thanks,
Heath

> If I comment out the '<cascade-persist/>' entry, all works fine. Note that
> in the above XML I've added the </schema> and <delimited-identifiers/>
> entries as well. Neither of these have an effect on the outcome (they could
> simply be removed). I was thinking that if the issue occurred for the
> cascade stanza that it might also occur for the <delimited-identifiers/>
> entry since the two are similar in their XML definition (XSD). However, this
> issue seems isolated to just the cascade stanza.
