      While booting Jenkins (standalone) I get this message:

          I'm unable to duplicate the issue as reported. Can you provide more details so that others can duplicate the issue from a fresh Jenkins installation? There are helpful scripts included in "How to report an issue".

          Steps that I took while trying to duplicate the issue:

          1. Create a plugins.txt file that lists the installed plugins and their versions
          2. Create a run-jenkins.sh shell script that downloads Jenkins 2.485 and the plugins from plugins.txt
          3. Run the run-jenkins.sh shell script and complete the setup wizard by creating a new user and installing no additional plugins
          4. Confirm that the Jenkins console output does not report a class not found exception with my Eclipse Temurin Java 21.0.5 installation on AMD64 Debian Linux
          5. Create and run a Pipeline job then view it in Blue Ocean to confirm that Blue Ocean is working as expected
