诊断这种崩溃的一个辅助手段是捕捉由各种线程抛出的异常并在退出之前通知该问题的依赖线程。这正是我在清单 2 中所做的。

清单 2. 把错误通知给客户机线程的示例
import java.util.Vector.

public class Server2 extends Thread {
Client2 client.
int counter.

public Server2(Client2 _client) {
this.client = _client.
this.counter = 0.
}

public void run() {
try {
while (counter < 10) {
this.client.queue.addElement(new Integer(counter)).
counter .
}
throw new RuntimeException("counter >= 10").
}
catch (Exception e) {
this.client.interruptFlag = true.
throw new RuntimeException(e.toString()).
}
}

public static void main(String[] args) {
Client2 c = new Client2().
Server2 s = new Server2(c).
c.start().
s.start().
}
}

class Client2 extends Thread {
Vector queue.
boolean interruptFlag.

public Client2() {
this.queue = new Vector().
this.interruptFlag = false.
}
