Java多线程中断的问题

Question

代码如下，为什么在中断之后将中断位清除后再进入阻塞，仍然会捕捉到中断异常？

public class InterruptDemo implements Runnable {
    public void run() {
        try {
            //中断当前线程
            Thread.currentThread().interrupt();
            boolean b = Thread.interrupted();
            System.out.println(b);  //true
            b = Thread.interrupted();
            System.out.println(b);  //false
            //进入阻塞
            Thread.currentThread().wait();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}
