I’ve posted a Jenkins Enhancement Proposal pull request with a plan to update the Jenkins Docker images from Java 8 to Java 11 as part of the August 25, 2021 LTS release of Jenkins 2.303.1.
We’re already working on the changes and the communication. We’d love to have additional insights from others about problems that may have been missed or issues that could cause us to reconsider making that change.
See the pull request and view the README file for details.
The pull request for the controller change in weekly Jenkins 2.307 has been submitted and is ready for review.
