Acknowledgement of transacted message in MessageListener should be inside delivery lock --------------------------------------------------------------------------------------- Key: JBAS-3634 URL: http://jira.jboss.com/jira/browse/JBAS-3634 Project: JBoss Application Server Issue Type: Task Security Level: Public (Everyone can see) Components: JMS service Affects Versions: JBossAS-4.0.5.CR1 Reporter: Adrian Brock Assigned To: Adrian Brock Fix For: JBossAS-4.0.5.GA The acknowledgement of a transacted message for a MessageListener should be inside the delivery lock. Otherwise the addition of the acknowledgement could be competing with other operations on the session, e.g. commit/rollback/recover. org.jboss.mq.SpyMessageConsumer::run() + // Try to obtain the session delivery lock + // This avoids concurrent delivery to message listeners in the same session as per spec + boolean gotDeliveryLock = false; + while (gotDeliveryLock == false) + { if (session.transacted) { // REVIEW: for an XASession without a transaction this will ack the message // before it has been processed. Plain message listeners // are not supported in a j2ee environment, but what if somebody is trying // to be clever? if (trace) log.trace("run() acknowledging message in tx mes=" + mes.getJMSMessageID() + " " + this); session.connection.spyXAResourceManager.ackMessage(session.getCurrentTransactionId(), mes); } - // Try to obtain the session delivery lock - // This avoids concurrent delivery to message listeners in the same session as per spec - boolean gotDeliveryLock = false; - while (gotDeliveryLock == false) - { -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
