Description
The members: int _green_zone; int _yellow_zone; int _red_zone; int _thread_threshold_step; of ConcurrentG1Refine should be some unsigned quantity, not signed. That will also allow removal of lots of safety "if (XY >= 0 && ...)" checks in the code. There is a preliminary patch attached that fixes that.
