safepoint accumulating time counter

[Brian Toal]

When I pull up jconsole and connect to a 1.8 runtime, I see
com.sun.management (not sun.management) and under the HotSpotDiagnostic
MBean I don't see any of the attributes mentioned.  Is there something I
need to do to enable the sun.management.HotspotRuntimeMBean?
