{quote}So if we had IP_MULTICAST_ALL set to 1, we'd get the old behavior ?{quote}

If I am looking at the appropriate API for this, the problem is that this API is available
only since JDK7:
http://docs.oracle.com/javase/7/docs/api/java/nio/channels/NetworkChannel...

Otherwise I don't see a  clean way to do this on JDK6.

                 Key: JGRP-1878
                 URL: https://issues.jboss.org/browse/JGRP-1878
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 3.2.12, 3.5
         Environment: OpenJDK8, OracleJDK8u40
            Reporter: Radoslav Husar
            Assignee: Radoslav Husar
            Priority: Minor
             Fix For: 3.2.14, 3.6

         Attachments: mcast.java

 Multicast discovery does not work on JDK8 when using different bind IP addresses. This
blocks EAP certification on JDK8.
 Steps to reproduce with draw, switch to JDK8:
 {noformat}
 export IP_ADDR=127.0.0.1
 ./draw.sh
 export IP_ADDR=192.168.1.10
 ./draw.sh
 {noformat}
 Everything works when binding to the same IP address or using JDK 6 or 7. Possibly a JDK8
bug..
