Yes, you are right. It makes sense to switch to Java 21 in the next couple of months (actually I never understood why one should not directly move from Java 11 to Java 21 for the controllers, as we also fully support Java 21 from the beginning of the Java 17 switch). The plan is to switch the weekly Jenkins releases to Java 21 in the middle of this year. See https://www.jenkins.io/blog/2023/11/06/introducing-2-2-2-java-support-plan/ If you find such wrong references of the Java version in out documentation it would be helpful if you can either create an issue in Jira or even better: click the „Improve the page“ button and fix the corresponding page by yourself. This helps us a lot as the documentation is spread along a lot of different files... Ulli -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
