    Description

      To turn off concurrent refinement you have to specify

      -XX:-G1UseAdaptiveConcRefinement -XX:G1ConcRefinementYellowZone=9999999 -XX:G1ConcRefinementRedZone=9999999 -XX:G1ConcRefinementGreenZone=9999999

      There should be an easier way to do this, we could introduce a new flag called -XX:-G1UseConcRefinement
