[jboss-jira] [JBoss JIRA] (JBMESSAGING-1896) MessagingClusterHealthMBean may block when stopping a node

MessagingClusterHealthMBean may block when stopping a node ---------------------------------------------------------- Key: JBMESSAGING-1896 URL: https://issues.jboss.org/browse/JBMESSAGING-1896 Project: JBoss Messaging Issue Type: Bug Components: JMS Clustering Affects Versions: 1.4.0.SP3.CP14, 1.4.8.SP3 Reporter: Yong Hao Gao Assignee: Yong Hao Gao Fix For: 1.4.0.SP3.CP15, 1.4.8.SP4 When a node is shunned from the node but at the same time its DB is also disconnected, the MessagingClusterHealthMBean will shut down the node in the jgroups thread. Because the shutdown happens in the process of view change, it will block on the MessagingPostOffice.stopViewUpdate() method. I will wait for the flag updateInProcess forever because it will never get a chance to update the flag.
