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

[Brian Stansberry]

What kind of extensibility are you thinking about?

I have no objection at all to the kind of simple JMX gateway resource 
David describes. If someone in the community wants to contribute that, 
that would be great.

I would object to it though if its presence became an excuse for 
subsystems not exposing their full management API via the standard 
management model. ;)
