Galen O'Sullivan updated GEODE-3555:
------------------------------------
    Description: 
If the number of client connections is above the configured maximum, new client 
connections will be rejected with a message that is meant for old clients and, 
to them, is unintelligible.

This can be seen with the following test added to 
{{RoundTripCacheConnectionJUnitTest}}:
{code}
  @Test
  public void testNewProtocolRespectsMaxConnectionLimit()
      throws IOException, InterruptedException {
    cache.close();

    CacheFactory cacheFactory = new CacheFactory();
    Cache cache = cacheFactory.create();

    CacheServer cacheServer = cache.addCacheServer();
    final int cacheServerPort = AvailablePortHelper.getRandomAvailableTCPPort();
    cacheServer.setPort(cacheServerPort);
    cacheServer.setMaxConnections(16);
    cacheServer.setMaxThreads(16);
    cacheServer.start();

    AcceptorImpl acceptor = ((CacheServerImpl) cacheServer).getAcceptor();

    Socket[] sockets = new Socket[16];

    for (int i = 0; i < 16; i++) {
      Socket socket = new Socket("localhost", cacheServerPort);
      sockets[i] = socket;
      Awaitility.await().atMost(5, TimeUnit.SECONDS).until(socket::isConnected);
      
socket.getOutputStream().write(CommunicationMode.ProtobufClientServerProtocol.getModeNumber());
    }

     try (Socket socket = new Socket("localhost", cacheServerPort)) {
       Awaitility.await().atMost(5, 
TimeUnit.SECONDS).until(socket::isConnected);
       OutputStream outputStream = socket.getOutputStream();
       outputStream
           
.write(CommunicationMode.ProtobufClientServerProtocol.getModeNumber());
       assertEquals(-1, socket.getInputStream().read());
     }
{code}

This can be traced to a call to {{         
ServerHandShakeProcessor.refuse(socket.getOutputStream(), ...}}
.
