Kevin Earls created AMQ-4857:
--------------------------------

             Summary: WSServlet.doWebSocketConnect throws NPE if called with 
null protocol
                 Key: AMQ-4857
                 URL: https://issues.apache.org/jira/browse/AMQ-4857
             Project: ActiveMQ
          Issue Type: Bug
            Reporter: Kevin Earls


I got the NPE shown below while working on a websocket demo.   
WebSocketFactory.acceptWebSocket calls WSServlet.doWebSocketConnect with the 
protocol hard coded to null.

java.lang.NullPointerException
