NamingContext.discoverServer shouldn't join multicast group
-----------------------------------------------------------

                 Key: JBNAME-47
                 URL: https://jira.jboss.org/jira/browse/JBNAME-47
             Project: JBoss Naming
          Issue Type: Bug
          Components: jnpserver
    Affects Versions: 5.0.4.GA
            Reporter: Brian Stansberry
            Assignee: Brian Stansberry
            Priority: Minor
             Fix For: 5.1.0.Beta1

NamingContext.discoverServer invokes the joinGroup method on the MulticastSocket is creates. It uses the socket to 1) send a multicast message and 2) received a UDP unicast reply. There is no need to join the group to send to it. Joining just raises the (slight) possibility of incorrectly receiving someone else's multicast discovery message instead of the desired unicast reply.
