controllers and agents on trusted.ci, cert.ci, and ci.jenkins.io controllers will be upgraded to use JDK25 at runtime

[Jay Francis]

Tuesday March 10  2026, starting at 09:00 UTC, the Jenkins controllers and agents on trusted.ci.jenkins.io, cert.ci.jenkins.io, and ci.jenkins.io will be upgraded to use JDK25 at runtime instead of JDK21.

This operation will require controller restarts and agent reconnections. A short service disruption is expected during the maintenance window.
