        public void onMessage(Message<String> msg) {
            atomicInteger.incrementAndGet();
            latch.countDown();

    topic.publish(message);
    assertOpenEventually(cp);
    topic.removeMessageListener(messageListenerId);
    topic.publish(message);
    assertOpenEventually(latch);
    assertEquals(3, atomicInteger.get());
}
