Cluster breaks after a MergeView is issued
------------------------------------------

                 Key: ISPN-398
                 URL: https://jira.jboss.org/jira/browse/ISPN-398
             Project: Infinispan
          Issue Type: Bug
          Components: Distributed Cache
    Affects Versions: 4.1.0.ALPHA2, 4.0.0.Final
            Reporter: Manik Surtani
            Assignee: Manik Surtani
            Priority: Critical
             Fix For: 4.1.0.BETA1, 4.1.0.Final


  * Start 2 demos (Infinispan 4.1 alpha2) with runGuiDemo.sh
  * Insert test=1 into A, you'll see it in B as well (numOwners=2)
  * Insert test=2 in B, you'll see it in A as well
  * Pull the plug on A (or B, doesn't matter)
  * Wait until both A and B are in their own clusters
  * Reinsert the plug
  * Insert test=3 in A: this won't get distributed to B !
  * Generate 50 random keys and values in either A or B: they won't
    get distributed to the other node !

As a matter of fact, nothing gets distributed anymore after pulling the plug !

Instead of pulling the plug, you can also uncomment <DISCARD.../> in jgroups-udp.xml and mimick a partition and subsequent merge this way, same effect.

Using only JGroups (e.g. Draw), this works fine.
