UDP: mcast_sock is not binding to bind_addr for reception of packets
--------------------------------------------------------------------

                 Key: JGRP-516
                 URL: http://jira.jboss.com/jira/browse/JGRP-516
             Project: JGroups
          Issue Type: Task
    Affects Versions: 2.4.1 SP3, 2.4.1 SP2, 2.4.1 SP1, 2.4.1
            Reporter: Bela Ban
         Assigned To: Bela Ban
             Fix For: 2.5


mcast_sock only bind to a NIC for *sending* of messages, but not for reception: it actually receives multicast packets on *all* interfaces (wildcard address 0.0.0.0). Code is UDP.createSockets():

mcast_sock=new MulticastSocket(mcast_port);

We should change this to:

SocketAddress saddr=new InetSocketAddress(bind_addr, mcast_port);
mcast_sock=new MulticastSocket(saddr);
