    Description

      G1 does not return a correct value for the CollectedHeap::millis_since_last_gc which is called from the JVM_MaxObjectInspectionAge, used by the RMI "distributed gc".

      This is a day-1 issue in G1 and an implementation should be added for completeness.

      ILW=
      L, objects may not be garbage collected as regularly as expected
      M, likelihood of setting sun.rmi.dgc.{client,server}.gcInterval is unclear, default value is 1h
      M, switch to a different GC
