GC Root:input or output parameters in native code
java.util.TaskQueue instance Leaking: UNKONWN Retaining 528 B in 2 objects TaskQueue.queue
java.util.TimerTask[] array Leaking: UNKONWN Retaining 512 B in 1 objects TimerTask[0]

有在onDestory方法中释放，但是无用，ondestory方法中调用了stopWS：
private void stopWS() {
if (stomp != null ) {
stomp.disconnect();
stomp.untopic(subscribeUrl);
stomp = null;
}
}
