    String messageListenerId = topic.addMessageListener(messageListener1);
    topic.addMessageListener(messageListener2);
    topic.publish(message);
    assertOpenEventually(cp);
    topic.removeMessageListener(messageListenerId);
    topic.publish(message);
    assertOpenEventually(latch);
    assertEquals(3, atomicInteger.get());
}
