I think the code change looks good. The new solution is easier to follow and better match the other GCs. But I have one question, have you done any testing to see how this changes the behavior of the Parallel Full GC for different scenarios. 

To me this isn't a simple refactoring as we actually change the behavior, so I would feel much more confident approving this knowing any potential impact it would have.
