We need better management information. A lot of the JSR-77 stuff is useful
information, the only problem was with how it was integrated, not really
tested, and not understood by the people working on the core stuff into
which this foreign code was interjected.


Where applicable this should be integrated via interceptors and/or aspects that
emit JMX notifications on which JSR-77 bean may be created. So the first
step is to replace the existing JSR-77 stuff with what we actually need to do
management and support of JBoss. For caches, pools, invocations, etc. there
needs to be low impact asynchronous events that allow for collection of this
information and rehashing statistically and historically.

I want this working in 3.2 as well so where the aspect stuff cannot be used
alternative approaches are needed.
