Once the critical mass has shifted, release a new version of the plugin parent POM that requires Jetty 12 or newer, including Java 17. This plugin parent POM should have the following characteristics:

• Its core version should be the first core that requires Jetty 12 EE 8.
• Its test harness version should support Jetty 12 EE 8 and Jetty 12 EE 9.
• It should require Java 17 or newer in maven.compiler.release.
• It should fix https://github.com/jenkinsci/plugin-pom/issues/936 by deleting the relevant lines. This will now be possible since the core version will be new enough to contain https://github.com/jenkinsci/jenkins/pull/9288.
