按照代码，很难触发线程可见性问题，但是如果改为

public void run() {
        while (!ready) {
            count++;
        }
        if (ready) {
            System.out.println("---> 结束啦");
        }
    }

 public void cancel() {
        ready = true;
        System.out.println("cancel..");
    }

这样任务就不能停止了，然后-server 加不加都一样。应该是混合编译的问题吧。是不是原代码加了 Tools.randomPause，导致jit失效？
