Semaphore waiting for permit even if node is shut down

[nyname00]

Hi Igniters,

I've got a problem with a semaphore that seems to wait for a permit even if
the node is already shut down. This behavior appears in a multi-node setup
where i try to shut down all nodes at the same time (using a poison-pill). 
The code below can be used to reproduce the behavior. You will notice that
there is no call on sem1#release() - this is because in my poison-pill
scenario there seems to be no way to get a handle to sem1. And since I was
under the impression that any semaphore gets released by Ignite when the
node crashes/is shut down, I was expecting an exception on sem2#acquire().

Any ideas? Best regards,
Mario

public static void main(String[] args) {
        Ignite i1 = Ignition.start(new IgniteConfiguration().setGridName("1"));

        System.out.println(">>> I1 STARTED");
        IgniteSemaphore sem1 = i1.semaphore("sem1", 1, true, true);
        System.out.println(">>> S1 READ");
        sem1.acquire();
        System.out.println(">>> S1 ACQUIRED");

        new Thread(() -> {
            IgniteSemaphore sem2 = i1.semaphore("sem1", 1, true, true);
            System.out.println(">>> S1 READ 2");
            sem2.acquire();
            try {
                System.out.println(">>> S1 ACQUIRED 2");
            } finally {
                sem2.release();
            }
        }).start();

        try {
            TimeUnit.SECONDS.sleep(2);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        System.out.println(">>> I1 CLOSING");
        i1.close();
        System.out.println(">>> I1 CLOSED");
    }
