4a3aa3a77a 6651256: jstack: DeleteGlobalRef method call doesn't lead to descreasing of global refs count shown by jstack
Jni_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'ed. When counting number of global reference, it counts all the handles on the chain list, which includes the already deleted ones.
