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 none of the JBC-created channels are created this way.
Workaround suggestion is to have JBC 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.
I marked this for SP4 but the real intent is it would be included in a CP release for AS 4.2.
