[jboss-jira] [JBoss JIRA] Commented: (JGRP-639) UDP: bind MulticastSocket to multicast address

[Bela Ban (JIRA)]

    [ http://jira.jboss.com/jira/browse/JGRP-639?page=comments#action_12396717 ] 
            
Bela Ban commented on JGRP-639:
-------------------------------

The solution is to use the multicast address to create the MulticastSocket: mcast_sock=new MulticastSocket(new InetSocketAddress(mcast_addr, mcast_port)).

If this throws an exception, we log it as WARN and retry with a null mcast_addr (this should usually work).

See http://wiki.jboss.org/wiki/Wiki.jsp?page=CrossTalking for details

> This doesn't work on Windows, so try-catch it and create new MulticastSocket with a wildcard bind address.
