Usually the first problem using replication is troubleshoot multicast in your machine/network as this is always environment depedent. Towards this end, this is JGroups Wiki that can help you out:

If multicast works, then you can also run the JBoss Cache unit test suite that comes with the distro (target run.batch and run.aop.batch).

    thanks very much for pointing me in the right direction. Indeed multicast on my machine was misconfgiured.

    I had static ip assignment and yet in my /etc/hosts file I did not tie the IP address to my hostname. This resulted in multicast only listening to loopback. Thats the best explanation I have for it with my limited network knowledge.

    Now it works as expected.
