Use of JGroups Multiplexer in AS 4.2.0

[brian.stansberry]

Bela, Vladimir and I had a discussion this AM and decided to defer integration of the JGroups multiplexer into AS 4.2.0. Primarily this because we want to ensure the issues discussed in http://jira.jboss.com/jira/browse/JGRP-415 are properly handled before we use the multiplexer in a supported AS release.

I will probably add the code hooks to ClusterPartition to support use of the multiplexer (they are already there in JBC 1.4.1), but 4.2.0 will not ship with the multiplexer sar. This approach will leave the potential for 4.2.0 installs to configure the multiplexer once all issues like JGRP-415 are resolved.

JBoss Messaging relies on the multiplexer to provide channels.

We're due to go GA at end of Feb, when this will be supported with platinum support.

Your point worried me a bit... are you saying that it's not ready/trusted for primetime yet?

Thanks for that reminder, Tim! I've got EJBs and web sessions on the brain this week.

The JGRP-415 issue means problems on one service can too easily affect another service.

I'll ping Bela to see how quickly this can be resolved. The code cutoff for AS 4.2 is meant to be Jan 31, so we didn't want to rush something in for that -- too close. What are your deadlines for when you'd want this in a JGroups

1) beta/CR release for testing.
2) GA
