Subject: Re: [jboss-as7-dev] JMX [was: Dear subsystem
owners/components leads ....]
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. ;)
That's exactly the slippery slope I don't want us to go down! From an Andiamo
perspective, we need ONE management layer that handles everything.
Let's keep this on track.
