Current implementation of JBoss Transaction(4.2.3.SP5_CP05) for EAP 4.3.0.GA_CP06 doesn't have a ExpiryScanner to clean up AtomicAction tx-logs. If there is an unrecoverable transaction (e.g. It might happen when JBoss instance is down before deleting tx-log after XAResource's commit is completed), periodic recovery will fail and WARN massages will be logged endlessly.
