Enabling JMX when using multiplexer.
------------------------------------

                 Key: JGRP-627
                 URL: http://jira.jboss.com/jira/browse/JGRP-627
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.6
            Reporter: Robert Newson
         Assigned To: Bela Ban


While debugging other issues (the disparity between cluster views and service views), I attempted to add JMX support. However, having looked at the code, it turns out that ObjectNames are formed incorrectly.

Caused by: javax.management.MalformedObjectNameException: Invalid character ':' in value part of property
	at javax.management.ObjectName.construct(ObjectName.java:602)
	at javax.management.ObjectName.<init>(ObjectName.java:1394)
	at org.jgroups.jmx.JmxConfigurator.registerChannel(JmxConfigurator.java:55)
	at org.jgroups.jmx.JmxConfigurator.registerChannel(JmxConfigurator.java:41)
	at org.jgroups.JChannelFactory.registerChannel(JChannelFactory.java:383)
	at org.jgroups.JChannelFactory.createMultiplexerChannel(JChannelFactory.java:297)
	at org.jgroups.JChannelFactory.createMultiplexerChannel(JChannelFactory.java:280)

It's attempting an ObjectName of the form "jgroups:name=Multiplexer:type=channel,cluster=blah" which is illegal.

I enabled JMX by calling;

channelFactory.setExposeChannels(true);
channelFactory.create();

Am I doing this wrong or does the JMX registration simply not work?

I can work around this with;

channelFactory.setDomain("jgroups")

but this doesn't group the JMX beans in the way the code intends.
