SwingWorker

[Alex]

I've create a thread using SwingWorker but when I call the interrupt()
method it doesn't get interrupted.
I've checked the execution path and t.interrupt() DOES get executed in the
SwingWorker interrupt() method shown below.

public void interrupt() {
Thread t = threadVar.get();
if (t != null) {
t.interrupt();
}
threadVar.clear();
}

What are you expecting to happen when interrupt() is called? What will
actually happen is that the thread will be interrupted during its next
interruptible call (such as Thread.sleep or Object.wait), but will
continue to run until then. Also, it can check for interruption by
polling the Thread.interrupted() method.

If you're expecting that the thread will be immediately interrupted from
whatever it is doing (even if that's not blocking on an interruptible
call), then it's your expectation rather than the behavior that's wrong.

Thanks, I understand now.
