These metrics are unfortunately not exported through JMX with Java 8.\n\nThis is really useful in production systems where you need to monitor STW (stop-the-world) pauses (`-XX:+PrintGCApplicationStoppedTime`).\n\n* getSafepointSyncTime()\n* getTotalSafepointTime()\n* getSafepointCount()\n\nThe need arose when we realized Java 8 did not export Safepoint stats through JMX.
