----------------------------------

             Summary: Websocket consumer cannot be started, because of NPE
                 Key: CAMEL-5908
                 URL: https://issues.apache.org/jira/browse/CAMEL-5908
             Project: Camel
          Issue Type: Bug
          Components: camel-websocket
    Affects Versions: 2.10.3
            Reporter: Igor Azarny
            Priority: Critical


Websocket consumer cannot be started for simple route 
        <camel:route>
            <camel:from uri="websocket://localhost:9998/cnt"/>
            <camel:to uri="stream:out"/>
        </camel:route>

Root cause:

Websoket component has not serlvet object. 

WebsoketComponent#line:170
// Don't provide a Servlet object as Producer/Consumer will create them later on
connectorRef = new ConnectorRef(server, connector, null);


WebsoketComponent#line:190
if (prodcon instanceof WebsocketConsumer) {
      // connect websocket consumer, to servlet
      connectorRef.servlet.connect((WebsocketConsumer) prodcon);
}
