当invokeAll()的线程数少于任务数时会发生什么情况?

我有以下代码:

ThreadPoolExecutor threadPoolExecutor = new ThreadPoolExecutor(
                                                10, // corePoolSize
                                                10, // maximumPoolSize
                                                10, // keepAliveTime
                                                TimeUnit.SECONDS, 
                                                new LinkedBlockingQueue<>()
                                        );

final List<Callable<MyResponse>> tasks = new ArrayList<>();
final CountDownLatch latch = new CountDownLatch(concurrency);

for (int i = 0; i < 50; i++) {
    tasks.add(() -> {
        latch.countDown();
        latch.await();

        return getResponse(); // Returns a MyResponse object.
    });
}

final List<Future<ThrottleResponse>> futures = threadPoolExecutor.invokeAll(tasks);

这辆车怎么了 invokeAll 方法?这个代码有没有死锁?为什么?我认为 threadPoolExecutor LinkedBlockingQueue 并从队列中轮询以执行任务,所以应该没有死锁,对吗?
