  "message": "6651256: jstack: DeleteGlobalRef method call doesn\u0027t lead to descreasing of global refs count shown by jstack\n\nJni_DeleteGlobalRef does not really release the jni handle, instead, set the handle point to JNIHandles::_deleted_handle which holds an oop instance (java/lang/Object) in Java heap and never be GC\u0027ed. When counting number of global reference, it counts all the handles on the chain list, which includes the already deleted ones.\n\nReviewed-by: zgu, sla, coleenp\n",
