[jboss-jira] [JBoss JIRA] Updated: (JBCACHE-836) TreeCache isCoordinator() returns incorrect value after clean shutdown of coordinator

[Brian Stansberry (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBCACHE-836?page=all ]

Brian Stansberry updated JBCACHE-836:
-------------------------------------

    Workaround Description: To get the coordinator Address, call getMembers() and take the first element in the returned Vector().  To see if the node is the coordinator, compare that Address to the one returned by a call to getLocalAddress().
                Workaround: [Workaround Exists]

Added a workaround for user code that calls isCoordinator() and getCoordinator().

> The code for determining who is the coordinator is calling ViewId.getCoordinator() to find the coordinator address.  This method actually returns the address of the node that *issued* the view, not that address of the current coordinator *in* the view.  When a node that is coordinator shuts down cleanly, one of the last things it does is issue the new view (without itself as a member).  For that view, ViewId.getCoordinator() returns the address of the node that has shut down, not the new coordinator.
