      • Enlist an XA and a LocalTransaction resource in a transaction
      • Have the XA resource "do nothing" so that the outcome is TwoPhaseOutcome.PREPARE_READONLY (and that there is only one item on the pendingList)
      • Have the LocalTransaction resource throw a ResourceException during commit()

      => warning is logged, EJB invocation succeeds

      Enlist an XA and a LocalTransaction resource in a transaction Have the XA resource "do nothing" so that the outcome is TwoPhaseOutcome.PREPARE_READONLY (and that there is only one item on the pendingList) Have the LocalTransaction resource throw a ResourceException during commit() => warning is logged, EJB invocation succeeds

      I have an entity manager (Oracle XA datasource) and a JCA resource adapter supporting LocalTransaction in one transaction.

      Following scenario:

      • An entity with values equal to those in the database is merged
      • The commit() of the local-tx resource fails and throws a ResourceException

      All that happens is a warning being logged:

      and the EJB invocation succeeds.

      I would expect the EJB to receive a RollbackException since the commit failed with XAException.XA_RBROLLBACK.

      Debugging BasicAction.prepare(), I can see that because the outcome of prepare is TwoPhaseOutcome.PREPARE_READONLY, one phase commit optimization is applied and onePhaseCommit() is called where the outcome TwoPhaseOutcome.ONE_PHASE_ERROR isn't considered an error as far as I understand.
      Then TwoPhaseOutcome.PREPARE_ONE_PHASE_COMMITTED is returned from BasicAction.prepare().

      I would never expect the EJB invocation to succeed if any participant in the transaction fails to commit.
