CyclicBarrier的附加同步

Question

我的代码就像：

  public class Test  {

final static CyclicBarrier CYCLIC_BARRIER = new CyclicBarrier(3, newRunnable() {
    @Override
    public void run() {
        System.out.println("Correctly three?Really?");
    }
});

public static void main(String[] args) {

    for (int i = 0; i <6 ; i++) {

        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    CYCLIC_BARRIER.await();
                    System.out.println(Thread.currentThread().getName());
                } catch (InterruptedException e) {
                    e.printStackTrace();
                } catch (BrokenBarrierException e) {
                    e.printStackTrace();
                }

            }
        }).start(); } }
 }

线程安全同步器搞得一团糟。这里有一些相当简单的代码，我希望得到如下输出：thread1，thread2，thread3和来自Runnable的消息， 但似乎存在竞争条件：

      Three threads? Really?
      Thread-4
      Three threads? Really?
      Thread-5
      Thread-2
      Thread-3
      Thread-1
      Thread-0

那么，我应该添加reentrantlock或其他什么来修复它吗？
