The 2.545 packages have been fixed (see details in https://github.com/jenkinsci/packaging/issues/729) and we are cleaning things up to ensure 2.546 has no issues with the JDK17 removal.
In addition: reminder that the LTS line 2.541.x should NOT have the JDK17 removal. I believe the jenkins/jenkins (Jenkins Core code) is being worked on by Mark, Kris, Alex, Uli and others to ensure that the branch "stable-2.541" has the proper commits. On the packaging/infra side, Hervé Le Meur and I are ensuring that our backports will also provide the JDK17 packaging. Please raise your voice if I misunderstood/mistook anything, or if you disagree of course :) Thanks all for your hard work!
