We need to check if the transaction is really in flight before returning status as committing. Previously code assumed, that if returned status is StatusCommitted, the only reason why the resource invoked replay_completion is that the transaction is in the process of committing.
However, as shown by the attached bugzilla, another work flow is also possible. Because Oracle database returned XAException.XAER_RMFAIL, second resource was committed successfully and the client was told that the transaction committed successfully. Recovery was left to sort out the issue with the database. Once the database resource invoked replay_completion and transaction manager saw the status of the transaction as StatusCommitted, it assumed that it is still in action even though there is no BasicAction available.
