WFLY-3805: JGroupsBroadcastGroupConfiguration Serialization Problem

Please someone take a look at this.
I have the same basic question as Paul; i.e. I don't understand the environment on the serialization target. But, for this part of the discussion, I'll just assume it's a requirement that some remote client may be completely unrelated to WildFly and needs to have a full protocol stack config serialized to it so it can use it to create a compatible channel.

That doesn't change WildFly's requirement that channel that are connected within the WildFly process use the WildFly integration. And AIUI this channel is going to be connected within the WF process, via BroadcastEndpoint.openClient() or BroadcastEndpoint.openBroadcaster().
