G1 young STW time in MBean

[Jakub Kubrynski]

Jesper already pointed me about JMC. The reason we're not using it is that
it cannot be integrated with our production monitoring. It's more problem
solving tool than continuous APM. So the question is if Oracle is going to
implement some MBeans for G1, and if not maybe we could propose JSR about
it?

Cheers,
Jakub
