------------------------------------------------------------------------------
src/hotspot/share/gc/g1/g1CollectedHeap.cpp
2067     _time_of_last_gc_ns = os::javaTimeNanos();

This variable seems really poorly named.

_time_for_millis_since_last_gc ?

Of course, millis_since_last_gc's name seems pretty poor too.

Maybe update those names as a followup.

Other than that naming issue, looks good.
