      Description

        This bug will attempt to resolve the problem described in JDK-8243962.

        The bug fix complements the work done in JDK-8245042 and JDK-8245113 to avoid having a JavaThread that is reading OS performance counters, which has proven to be very slow on certain platforms and circumstances, stall a pending safepoint synchronization.

        Transitions will be performed for periodic events EventCPULoad and EventThreadContextSwitchRate.
