Race condition on ServerConsumerEndpoint creation ------------------------------------------------- Key: JBMESSAGING-490 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-490 Project: JBoss Messaging Issue Type: Bug Reporter: Ovidiu Feodorov Assigned To: Ovidiu Feodorov Priority: Minor Fix For: 1.0.1.CR4 Because "started" is not declared volatile, there's a minor race condition between the construction of the the ServerConsumerEndpoint on a started connection, and delivery request. Test fragment: conn.start(); Session sess = conn.createSession(true, Session.SESSION_TRANSACTED); .... MessageConsumer cons1 = sess.createConsumer(queue); Trace: 2006-08-04 10:05:24,050 23375 DEBUG [org.jboss.jms.server.endpoint.ServerSessionEndpoint] (main:) creating consumer for JBossQueue[Queue], selector null, subscription null 2006-08-04 10:05:24,050 23375 TRACE [org.jboss.jms.server.endpoint.ServerConsumerEndpoint] (main:) creating consumer endpoint -2147483430 2006-08-04 10:05:24,050 23375 TRACE [org.jboss.messaging.core.ChannelSupport] (main:) CoreQueue[1] attempting to add receiver ConsumerEndpoint[-2147483430] 2006-08-04 10:05:24,050 23375 TRACE [org.jboss.messaging.core.ChannelSupport] (main:) receiver ConsumerEndpoint[-2147483430] added 2006-08-04 10:05:24,050 23375 DEBUG [org.jboss.jms.server.endpoint.ServerConsumerEndpoint] (main:) ConsumerEndpoint[-2147483430] created 2006-08-04 10:05:24,050 23375 TRACE [org.jboss.jms.server.endpoint.ServerConsumerEndpoint] (Thread-3:) ConsumerEndpoint[-2147483439] receives reference 3584 for delivery 2006-08-04 10:05:24,050 23375 TRACE [org.jboss.jms.server.endpoint.ServerSessionEndpoint] (main:) SessionEndpoint[-2147483431] caching consumer -2147483430 2006-08-04 10:05:24,050 23375 DEBUG [org.jboss.jms.server.endpoint.ServerConsumerEndpoint] (Thread-3:) ConsumerEndpoint[-2147483439] NOT started yet!
