             Summary: [Java Broker] Add functionality to prevent unintended HA node creation
and mechanisms to react on intruder HA nodes
                 Key: QPID-5867
                 URL: https://issues.apache.org/jira/browse/QPID-5867
             Project: Qpid
          Issue Type: Improvement
          Components: Java Broker
            Reporter: Alex Rudyy
            Assignee: Alex Rudyy


Add functionality to prevent unintended node creation and mechanisms to react on intruder
nodes

    New HA VH attribute permittedNodeList
    Nodes register the contents of this attribute as app-state
    On adding a new node to the griup, the node must check to see its node address is included
in the app-state, if not, refuse to join
    All nodes periodically (BDBHAVHN has a thread dedicated to the purpose or reuse node discovery
thread?) check to see if nodes exist that do not appear in the app-state. If so VHN will close
env and go into ERROR state.
    If in management mode don't periodically check the PNL, thus allowing an intruder to be
removed.
