> The writer of this test misunderstood ThreadPoolExecutor.
> The test adds Threads as tasks to a ThreadPoolExecutor and then calls join on 
> the Thread objects. But these are not the running threads, it work by pure 
> accident, because Thread happens to implement Runnable.
> {code}
> pool.submit(threads.get(0));
> ...
> threads.get(0).join();
> {code}
> The join will always return immediately, because the thread never ran.
> This should instead synchronize on the Future returned from submit instead, 
> otherwise there is no guarantee that the threads in the pool actually 
> finished.
