因为需求简单，想简单使用下timer来实现一个定时任务，过程中出现了如下问题，有点丈二和尚摸不着头脑，
一直报一下错误，百度了下说是线程已经关闭了，难道是nutz框架自动处理关闭的吗
Source not found for TimerThread.run() line: not available

	if(redisService.hget(Constants.RoomPrefix+roomId, Constants.TimeDownField) == null){//还没开始倒计时
	    		redisService.hset(Constants.RoomPrefix+roomId, Constants.TimeDownField, "1");
	    		//开始游戏前的room和user对象的信息更新和第一轮发牌
	    		final Timer timer = new Timer(); 
	    		TimerTask myTimeTask = new TimerTask(){

					@Override
					public void run() {
						// TODO Auto-generated method stub
						 action2Round1(roomId, resp, timer);
					}
					
	    		};
	    		long timestamp = 3000; 
	    		/** 
	    		* myTimeTask 指定执行的线程 date 指定第一次日期执行的时间 timestamp 指定每格多久再次执行一次
	    		*/
	    		timer.schedule(myTimeTask, timestamp);
	    		return true;
	    	}

这是timertask任务的内容，每次执行到这里有报线程已经结束

            	Set<String> openIdsInGame = r.getOpenIdsInGame();
            	
        		if(openIdsInRoom != null && openIdsInRoom.size() > 1){
        			List<Poker> pokerList = poker.createPoker();//初始化一副牌
        			Poker maxPoker = null;

        						maxPoker = pokerAry[2];
    		        			redisService.hset(Constants.RoomPrefix+roomId, Constants.BeforeIndexField, String.valueOf(u.getIndex()));
        					}
        					
        					u.setPokerAry(pokerAry);//每个玩家自己的扑克牌

        					redisService.set(openId, u.toString());
        					fp1.setv(String.valueOf(u.getIndex()), pokerAry[2]);
        				}
        			}

        			resp.setv("action", "frontPoker1");
					resp.setv("msg", fp1); 
					sendAllSync(resp, roomId);
        			r.setPokerList(pokerList);
        			redisService.hset(Constants.RoomPrefix+roomId, Constants.RoomField, r.toString());
        		}else{
        			resp.setv("action", "noEnoughUser");
