Yes, I see that now. Do you have a test to check it is working so a RHEL bugzilla can be filed?

Yes, I mean network interface not be specified as things seem to always work that way. And that leads to multicast setup not being so much error prone.
Do you see any drawbacks of having that by default for JBoss AS 5?
