Нить.isInterrupted не работает, нить.прерывается ли

Следующая программа демонстрирует проблему (последняя версия JVM & whatnot):

public static void main(String[] args) throws InterruptedException {
    // if this is true, both interrupted and isInterrupted work
    final boolean withPrint = false;

    // decide whether to use isInterrupted or interrupted.
    // if this is true, the program never terminates.
    final boolean useIsInterrupted = true;

    ExecutorService executor = Executors.newSingleThreadExecutor();
    final CountDownLatch latch = new CountDownLatch(1);
    Callable<Void> callable = new Callable<Void>() {
        @Override
        public Void call() throws Exception {
            Random random = new Random();
            while (true) {
                if (withPrint) {
                    System.out.println(random.nextInt());
                    System.out.flush();
                }
                if (useIsInterrupted)
                {
                    if (Thread.currentThread().isInterrupted())
                        break;
                }
                else
                {
                    if (Thread.interrupted())
                        break;
                }
            }
            System.out.println("Nice shutdown");
            latch.countDown();
            return null;
        }
    };
    System.out.println("Task submitted");
    Future<Void> task = executor.submit(callable);
    Thread.sleep(100);
    task.cancel(true);
    latch.await();
    System.out.println("Main exited");
    executor.shutdown();
