        @Override
        public void memberRemoved(MembershipEvent membershipEvent) {
            memberRemovedLatch.countDown();
        }

    try {
        context.commitTransaction();

        txnRollbackLatch.countDown();
    }
    assertOpenEventually(txnRollbackLatch);
    assertOpenEventually(memberRemovedLatch);
    final IQueue<Object> q = client.getQueue(queueName);
    assertNull(q.poll());
    assertEquals(0, q.size());
}
