多线程测试，内存溢出，为什么java没给小弟我自动回收垃圾

import java.util.Date;
import java.util.Timer;
import java.util.TimerTask;

public class T {
    private static int count=0;
    /**
     * @param args
     */
    public static void main(String[] args) {
        
        class MyTimerTask extends TimerTask{

            @Override
            public void run() {
                count=(count+1)%2;
                System.out.println(Thread.currentThread().getName()+" count:"+count);
                
                new Timer().schedule(new MyTimerTask(), 0+count*2);
            }
            
        }
        TimerTask task=new MyTimerTask();
        
        System.out.println("开始");
        new Timer().schedule(task, 3000);
        
        while(true){
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            System.out.println("    "+Thread.currentThread().getName()+" "+new Date().getSeconds());
            
        }
    }
