CLI, Agent -websockets DeploymentException: Handshake response not received on jdk-11

XMLWordPrintable

    • 2.317

      Testing CLI, agent connections with the new '-websocket' functionality added by
      JEP-222.

       

      Jetty access log shows:

      172.18.0.3 - - [25/Feb/2020:01:48:06 +0000] "GET /cli/ws HTTP/1.1" 101 0 "-" "-"

      CLI output:

      javax.websocket.DeploymentException: Handshake response not received.

      When I attach a debugger to the Jenkins server it seems to get stuck here:
