    NPE with SSO in cluster

    Prabhat Jha Master

      I have a 2-node cluster with EAP 4.3 CP04 running portal with apache mod_jk in front. I have turned on org.jboss.web.tomcat.service.sso.ClusteredSingleSignOn in jboss-web.deployer. When failover happens, I see following in server log:

      4:59:18,550 ERROR [TreeCacheSSOClusterManager] Caught exception cleaning sessions from dead cluster members from SSOs
      java.lang.NullPointerException
       at org.jboss.web.tomcat.service.sso.TreeCacheSSOClusterManager$DeadMemberCleaner.run(TreeCacheSSOClusterManager.java:1493)
       at org.jboss.util.threadpool.RunnableTaskWrapper.run(RunnableTaskWrapper.java:148)

       at java.lang.Thread.run(Thread.java:595)
      


      Thanks for creating https://jira.jboss.org/jira/browse/JBPAPP-1865. What could be the cause?
