Hello,

we are using Optimistic Lock Exception in a stateful bean managed transaction.

I am wondering that there is no Optimistic Lock Exception is thrown after em.merge

The Optimistic Lock Exception is primary thrown on em.flush - is this right?

A similar problem is described on
http://www.nabble.com/Optimistic-Lock-Exception-expected-td22742662.html#a22742662


See serveroutput: The EclipseLink-5006-Exception is thrown after an em.flush

14:03:11,750 ERROR [BMTInterceptor] BMT stateful bean 'ModelFacade' did not complete user transaction properly status=STATUS_MARKED_ROLLBACK


And by this Exception the transaction's status is set to status=STATUS_MARKED_ROLLBACK.
The transaction can no longer be used.

I want to use this transaction further and wrap the OptimisticLockException into an MyApplicationException
(see serveroutput).

But no change!


Any Ideas ?
