Description
In g1CollectedHeap.cpp at the end of the G1FreeCollectionSetTask::work() method, young_time is reported as G1GCPhaseTimes::NonYoungFreeCSet.
if (has_non_young_time) {
timer->record_time_secs(G1GCPhaseTimes::NonYoungFreeCSet, worker_id, young_time);
}
This screws up timing predictions as this value is used for predicting non-young region elapsed time.
