Cross-cluster cross-talk on JBM-DATA channel
--------------------------------------------

                 Key: JBAS-6307
                 URL: https://jira.jboss.org/jira/browse/JBAS-6307
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Clustering, JMS (JBoss Messaging)
    Affects Versions: JBossAS-5.0.0.GA
            Reporter: Brian Stansberry
            Assignee: Brian Stansberry
             Fix For: JBossAS-5.0.1.CR1


The configuration syntax in the jbm-data protocol stack config's MPING.mcast_addr attribute is not understood by the JGroups parser; it's syntax only supported by the String property replacement code in jboss-common-core.jar.

<MPING timeout="5000" mcast_addr="${jboss.messaging.datachanneludpaddress,jboss.partition.udpGroup:228.6.6.6}"

will be evaluated by JGroups as "use value for system property 'jboss.messaging.datachanneludpaddress,jboss.partition.udpGroup', if not found use 228.6.6.6".  Which results in 228.6.6.6.

Fix is to replace with 

<MPING timeout="5000" mcast_addr="${jboss.partition.udpGroup:228.6.6.6}"

in which case setting -u at AS startup will set jboss.partition.udpGroup, which JGroups will find and use.
