[jboss-as7-dev] JMX [was: Dear subsystem owners/components leads ....]

[Brian Stansberry]

We already expose a JMX connector. And we will expose all the management 
resources as mbeans. So all our management resources will be available 
via JMX, as will be any stuff that 3rd parties choose to put in JMX.

So the only issue is whether we provide a simple JMX gateway resource to 
provide access to 3rd party JMX stuff via the domain management API and 
thus the CLI. I already said I have no objection to that. It's not a 
priority that I want to allocate any resources to though in the next few 
months; we have a lot of tasks to get done.
