      Replace the complex syntax like:
      mcast_addr="${jboss.messaging.datachanneludpaddress,jboss.partition.udpGroup:228.6.6.6}"
      with:
      mcast_addr="${jboss.partition.udpGroup:228.6.6.6}"
      Prefer keeping the jboss.partition.udpGroup property as that can easily be set from the command line via the -u or --udp startup option.

      Description

      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.
