The JON team wants to be able to monitor all channels in the AS via JMX (see JGRP-207). But, channels only get registered in JMX if they are created via a call to JChannelFactory.createMultiplexerChannel(). AS 4.2 currently doesn't use the multiplexer, so the ClusterPartition-created channel is not created this way.

Workaround suggestion is to have ClusterPartition register the channel it creates via a call to org.jgroups.jmx.JmxConfigurator.registerChannel(). An unregisterChannel call would have to be added any time the channel is closed as well.
