    Description

      The GCPhaseParallel JFR event is used for a lot of different phases in G1. One such phase is the scan heap roots. In this phase the event is sent once per region instead of once per worker and since all workers work on all regions this leads to way to many events.

      Fix to only send one event per worker.
