title: ActiveMQ Websocket transport with maximumConnections
body: <p>I'm trying to load test ActiveMQ using the default websocket connector: </p>
  
  <pre><code>&lt;transportConnector name="ws" uri="ws://0.0.0.0:61614?maximumConnections=1000&amp;amp;wireFormat.maxFrameSize=104857600"/&gt; 
  </code></pre>
  
  <p>However, despite the <code>maximumConnections</code> attribute, I managed to have more 
  than 2000 consumers successfully connected. I can see the 2000+ connections 
  using <code>netstat -an</code>. </p>
  
  <p>Do the transport connection attributes work for this websocket transport? 
  Or have I misunderstood something?</p>
