jtax subordinate TransactionImple confuses TwoPhaseOutcome and ActionStatus

                 Key: JBTM-506
                 URL: https://jira.jboss.org/jira/browse/JBTM-506
             Project: JBoss Transaction Manager
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 4.5
            Reporter: Jonathan Halliday
            Assignee: Mark Little
             Fix For: 4.6

In some methods of com.arjuna.ats.internal.jta.transaction.arjunacore.subordinate.TransactionImple, code of the form

 int res = subAct.doFoo();
case ActionStatus.Bar:

is found. This is incorrect, as the methods on SubordinateAtomicAction return TwoPhaseOutome not ActionStatus.  In the JTA the SubordinateAtomicAction returns ActionStatus which is probably where the confusion arises, so arguably it's actually the JTAX version of SubordinateAtomicAction which is at fault, not the TransactionImple.

Since the case statements will need reworking anyhow, it's probably worth looking that the way 'try to commit but actually have to rollback' is handled. In the JTA this throws RollbackException as the rollback is clean. In the JTAX it results in a HeuristicRollback due to the way the states and exceptions are mapped. This is perhaps less user friendly than it could be.
