      Description

      With WebSocket connectors defined e.g.

      <transportConnectors>
          <transportConnector name="ws"
                              uri="ws://0.0.0.0:61614?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/>
          <transportConnector name="wss"
                              uri="wss://0.0.0.0:61615?transport.wantClientAuth=true&amp;maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/>
      </transportConnectors>
      

      A request to https://127.0.0.1:61615/ gives HTTP 500 Internal Server Error with the following in the log:

      This occurs because no default servlet is defined. Either ActiveMQ should not attempt to forward GET requests to the default servlet, or the embedded Jetty instances should be configured with a proper default servlet.
