Worked on the MicrosoftDocs/azure-dev-docs repository to deliver a targeted runtime upgrade for Jenkins Linux VM environments. The main feature involved replacing the existing OpenJDK 11 runtime with OpenJDK 17, ensuring compatibility with newer Jenkins versions and Java-dependent features. This upgrade required careful planning around Java runtime management and CI/CD configuration, with a focus on version-based upgrade strategies and commit traceability. The work was documented using Markdown, emphasizing clarity and reproducibility. No bugs were fixed during this period, and no regressions were observed, resulting in improved security, reduced maintenance, and better alignment with the supported Java ecosystem for CI workflows.
