Oracle has stated that Java WebStart will not be supported past Java SE 8. This may affect launching Agents manually via JNLP.

          My proposal is to detach it from the Jenkins Core as a part of JENKINS-51820

          I tested it on Java 11.
          The UI still works, but obviosly it does nothing with modern Java versions.
          The agents are still able to connect using CLI.

          AFAIK this has been fixed/clarified in Jenkins 2.153+ thanks to markewaite in https://github.com/jenkinsci/jenkins/pull/3766.

          https://jenkins.io/redirect/java11-java-web-start :

          > In March 2018, Oracle announced it will not include Java Web Start in Java SE 11 (18.9 LTS) and later. Developers will need to transition to other deployment technologies[3].

           

          Given the technology is not anyway available "upstream", the Jenkins Project can obviously not provide support anymore to this.

           

          Thanks!
