Agenda

• The Jenkins infrastructure team has switched the Jenkins Core release to use JDK21 instead of JDK17 starting with the weekly release 2.514 (it’s been 3 weeks, no issue).
  • We’ll release JDK17 compatible bytecode until we don’t support JDK17 anymore (around March 2026).
• DockerHub Automatic email about Open Source subscription canceled
  • https://groups.google.com/g/jenkins-infra-team/c/HRQfC9Mleqc/m/MYBFtI_MAAAJ
• Java Patch Day is on July 15th.
• Java 25
  • Temurin supplies JDK 25 early access binaries
  • The infra team has started working on it.
    • The task is available in the helpdesk
    • We’re currently facing an issue with Goss, which isn’t correctly handling the JDK25 tests for Windows—it reports everything as okay even when the Windows JDK25 Temurin build isn’t available.
  • We are trying to compile the top 250 plugins with JDK25
    • Results there: Jenkins PR Tracker
