@Override

    ReflectorMessageQueue msgQueue = reflector(ReflectorMessageQueue.class, realQueue);

@Override
  public void reset() {
    ReflectorMessageQueue msgQueue = reflector(ReflectorMessageQueue.class, realQueue);
    msgQueue.setMessages(null);
    msgQueue.setIdleHandlers(new ArrayList<>());
    msgQueue.setNextBarrierToken(0);
  }
