                 Key: JGRP-862
                 URL: https://jira.jboss.org/jira/browse/JGRP-862
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.6.6
         Environment: Linxu AS4, Jgroups-2.6.6 , Java version "1.5.0_10"
            Reporter: Brendan Doherty
            Assignee: Bela Ban

Using the multicast send/receiver test application, all on the same physical machine with the following parameters -Djava.net.preferIPv4Stack=true -mcast_addr <AS BELOW>  -bind_addr <LAN IP  address>

Create one sender on 239.197.0.1
Create one receiver on 239.198.0.1
Create a second receiver on 239.199.0.1

Send a message, as expected neither of the receivers observe the message.

Create a third receiver on 239.197.0.1
Send a message, all three senders now receive the message

Is this the expected behaviour?
