> When GroupMember connects a JGroups Channel, it passes null to Channel.connect(String).  It needs to pass the same value that it passes as the "id" param to ChannelFactory.createMultiplexerChannel(String stack_name, String id, boolean register_for_state_transfer, String substate_id), i.e.
> ${jboss.partition.name:DefaultPartition}-JMS-CTRL and ${jboss.partition.name:DefaultPartition}-JMS-DATA
> Passing null has worked solely due to an internal quirk in JGroups' MuxChannel implementation of the Channel interface.  If JGroups internally provides a shared transport JChannel instead of a MuxChannel, it will fail:
