Amends pull request: * https://github.com/jenkinsci/jenkins/pull/11148 The 2+2+2 Java support plan recommends that we drop support for a Java line after two years so that we're only supporting two Java versions at a time. Refer to the blog post: * https://www.jenkins.io/blog/2023/11/06/introducing-2-2-2-java-support-plan/ Also refer to the Jenkins Enhancement Proposal pull request (incomplete): * https://github.com/jenkinsci/jep/pull/400 Testing done: * None. Relying on the existing behavior that I've seen from the Java 17 administrative monitor. It is now shown to users to warn them that we plan to drop Java 17 support by the end of March 2026
