WFLY-3805: JGroupsBroadcastGroupConfiguration Serialization Problem

Please someone take a look at this.
Sure they are different. The one in wildfly does something more. But the point is if the bare 'protocol stack' is the same, the channels should be able to communicate with each other, unless you force all remote clients to use the wildfly flavor channels (like the MuxChannel that extends JChannel but not actually part of JGroups).
