Java Object.wait() jvm的bug

在使用java线程的时候,经常会用到wait方法,如果在调用wait方法的时候被中断,jvm会捕获这个中断不断调用wait 指令

这时候即使你使用interrupt 发法来中断都是没有用的.

需要对wait方法做一些封装,捕获异常,然后停止执行它

public static void wait(Object obj) {
        boolean interrupted = true;
        while (interrupted) {
            interrupted = false;
            try {
                obj.wait();
            }
            catch (InterruptedException e) {
                interrupted = true;
            }
        }
    }

    public static void wait(Object obj, int timeout) {
        boolean interrupted = true;
        long startTime = System.currentTimeMillis();
        int sleepTimeout = timeout;

        while (interrupted) {
            interrupted = false;
            try {
                obj.wait(sleepTimeout);
            }
            catch (InterruptedException e) {
                interrupted = true;
                long now = System.currentTimeMillis();
                sleepTimeout -= now - startTime;
                startTime = now;
                if (sleepTimeout < 0) {
                    interrupted = false;
                }
            }
        }
    }
