I see that there is websocket endpoint which works out fins with Java tests. In logs I see
Connecting to: ws://127.0.0.1:8080/76f48a44-0af8-444c-ba97-3f1ed34af
I had to use this command to make it work:
$ curl -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Host: echo.websocket.org" -H "Origin: http://www.websocket.org" -H "Sec-WebSocket-Version: 13" -H 'Sec-WebSocket-Key: +onQ3ZxjWlkNa0na6ydhNg==' http://www.websocket.org
I am using Jetty, and if I didn't add the Sec-WebSocket-Version/Sec-WebSocket-Key doesn't work. Just for the record.
