The example of using emitters/receivers of kernel events, mentioned in docs, is needed. (I've not found any in docs/examples)
a) How to register listener( whether MC may do it automatically on discoveriong some well-known interface?)
b) How to send event from bean ?
The events is experimental.
It is little more than a port of JMX Notification api, so if you are familiar with that....
You would be better off using AOP (which is likely the way we are going to go).
