When live-slave fails-back to master, it turns off everything down, even its console

    • Release Notes
    • In high-availability configurations, AMQ Console is now accessible when a slave broker returns control to the master broker. Previously, AMQ Console would become unavailable for the slave broker when it gave control back to the master broker.

      1) Set up HA pair with slave <allow-failback>true</allow-failback>
      2) Kill master
      3) Make sure slave becomes live
      4) Start master again, slave gives control to master and becomes a slave
      5) Console of slave (backup now) becomes inaccessible

      When slave goes from live back to backup, it shuts down everything. Even its own hawtio console. That should not happen. By default console is always available.
