NullPointerException within DefaultClusteredPostOffice.handleMessagePullResult() -------------------------------------------------------------------------------- Key: JBMESSAGING-978 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-978 Project: JBoss Messaging Issue Type: Bug Components: JMS Clustering Affects Versions: 1.2.0.SP1 Environment: CentOS 4, JBoss AS 4.0.5, Sun JDK 1.5.07, MySQL 5.x for persistence. Six node cluster. Reporter: Ray Ploski Assigned To: Tim Fox Attachments: DefaultClusteredPostOffice.java After sending about 10,000 messages through a clustered JMS deployment we received the following error, locking up the topic. I worked around it by adding a null check to the condition within handleMessagePullResult(). Fix is for line 968 of org.jboss.messaging.core.plugin.postoffice.cluster.DefaultClusteredPostOffice is listed at the end of the description. 2007-05-31 11:41:39,130 ERROR @IncomingMessageHandler (channel=DefaultPostOffice) [DefaultClusteredPostOffice] Caught Exception in Receiver java.lang.NullPointerException at org.jboss.messaging.core.plugin.postoffice.cluster.DefaultClusteredPostOffice.handleMessagePullResult(DefaultClusteredPostOffice.java:968) at org.jboss.messaging.core.plugin.postoffice.cluster.PullMessageResultRequest.execute(PullMessageResultRequest.java:105) at org.jboss.messaging.core.plugin.postoffice.cluster.DefaultClusteredPostOffice$DataReceiver.receive(DefaultClusteredPostOffice.java:2461) at org.jgroups.JChannel.up(JChannel.java:1102) at org.jgroups.stack.ProtocolStack.up(ProtocolStack.java:377) at org.jgroups.stack.ProtocolStack.receiveUpEvent(ProtocolStack.java:393) at org.jgroups.stack.Protocol.passUp(Protocol.java:538) at org.jgroups.protocols.pbcast.GMS.up(GMS.java:771) at org.jgroups.stack.Protocol.receiveUpEvent(Protocol.java:488) at org.jgroups.protocols.pbcast.GMS.receiveUpEvent(GMS.java:791) at org.jgroups.stack.Protocol.passUp(Protocol.java:538) at org.jgroups.protocols.VIEW_SYNC.up(VIEW_SYNC.java:154) at org.jgroups.stack.Protocol.receiveUpEvent(Protocol.java:488) at org.jgroups.stack.Protocol.passUp(Protocol.java:538) at org.jgroups.protocols.FRAG.up(FRAG.java:168) at org.jgroups.stack.Protocol.receiveUpEvent(Protocol.java:488) at org.jgroups.stack.Protocol.passUp(Protocol.java:538) at org.jgroups.protocols.pbcast.STABLE.up(STABLE.java:258) at org.jgroups.stack.Protocol.receiveUpEvent(Protocol.java:488) at org.jgroups.stack.Protocol.passUp(Protocol.java:538) at org.jgroups.protocols.UNICAST.handleDataReceived(UNICAST.java:476) at org.jgroups.protocols.UNICAST.up(UNICAST.java:206) at org.jgroups.stack.Protocol.receiveUpEvent(Protocol.java:488) at org.jgroups.stack.Protocol.passUp(Protocol.java:538) at org.jgroups.protocols.pbcast.NAKACK.up(NAKACK.java:569) at org.jgroups.stack.Protocol.receiveUpEvent(Protocol.java:488) FIX: if (remoteQueue == null || remoteNodeId != remoteQueue.getNodeId() )
