[jboss-jira] [JBoss JIRA] Updated: (JBAS-3194) Proxies for HAServiceMBeanSupport subclass unbound across cluster when any instance undeployed

Proxies for HAServiceMBeanSupport subclass unbound across cluster when any instance undeployed ---------------------------------------------------------------------------------------------- Key: JBAS-3194 URL: http://jira.jboss.com/jira/browse/JBAS-3194 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Clustering Affects Versions: JBossAS-4.0.4.CR2, JBossAS-4.0.3 SP1, JBossAS-4.0.3 Final Reporter: Brian Stansberry Assigned To: Scott Marlow Fix For: JBossAS-4.0.6.CR1 ProxyFactoryHA registers a JMX notification listener for the shutdown of its target service and removes the proxy from JNDI on receipt of the notification. HAServiceMBeanSupport broadcasts its JMX notifications *across the cluster*. The effect of this is that the ProxyFactoryHA on all cluster nodes will receive the notification when any one instance of the service undeploys. The effect is all proxies across the cluster are removed from JNDI. Test org.jboss.test.cluster.jmx.test.HAInvokerUnitTestCase demonstrates this. Following is a deliberately created stacktrace showing the origin of a notification that caused an invalid removal from JNDI: 2006-05-08 01:51:53,703 DEBUG [org.jboss.proxy.generic.ProxyFactoryHA] About to stop: disabling remote access to mbean jboss.test:service=HAService 2006-05-08 01:51:53,703 DEBUG [org.jboss.proxy.generic.ProxyFactoryHA] java.lang.Exception: stacktrace java.lang.Exception: stacktrace at org.jboss.proxy.generic.ProxyFactoryHA.containerIsAboutToStop(ProxyFactoryHA.java:169) at org.jboss.proxy.generic.ProxyFactoryHA$StateChangeListener.handleNotification(ProxyFactoryHA.java:231) at sun.reflect.GeneratedMethodAccessor3.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.mx.notification.NotificationListenerProxy.invoke(NotificationListenerProxy.java:153) at $Proxy10.handleNotification(Unknown Source) at org.jboss.mx.util.JBossNotificationBroadcasterSupport.handleNotification(JBossNotificationBroadcasterSupport.java:127) at org.jboss.mx.util.JBossNotificationBroadcasterSupport.sendNotification(JBossNotificationBroadcasterSupport.java:110) at org.jboss.ha.jmx.HAServiceMBeanSupport._receiveRemoteNotification(HAServiceMBeanSupport.java:393) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jgroups.blocks.MethodCall.invoke(MethodCall.java:330) at org.jboss.ha.framework.server.HAPartitionImpl.handle(HAPartitionImpl.java:1017) at org.jgroups.blocks.RequestCorrelator.handleRequest(RequestCorrelator.java:597) at org.jgroups.blocks.RequestCorrelator.receiveMessage(RequestCorrelator.java:497) at org.jgroups.blocks.RequestCorrelator.receive(RequestCorrelator.java:320) at org.jgroups.blocks.MessageDispatcher$ProtocolAdapter.up(MessageDispatcher.java:725) at org.jgroups.JChannel.up(JChannel.java:1041) 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.STATE_TRANSFER.up(STATE_TRANSFER.java:141) at org.jgroups.stack.UpHandler.run(Protocol.java:60)
