RFR - [RFE] JDK-8007141 : Introduce Dynamic MBean exposing the perf counters

[Erik Gahlin]

Hi Harsha,

How will perf counters be supported?

Can they be removed at anytime, or only at major releases etc. Do we 
have tests for them? I think it would be good know, and perhaps state 
somewhere so we don't break people's code.
