Hi, I'm LGSW_Sam's colleague. We have now updated jboss cache to 1.4.1GA. We are still getting | 10:49:34,285 WARN [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator_4] TwoPhaseCoordinator.afterCompletion - failed for com.arjuna.ats.internal.jta.resources.arjunacore.SynchronizationImple@247e247e | Those NPE problems went away.
