Mar 1, 2026March 2026 monthly summary for CorfuDB/CorfuDB focusing on Java version upgrade and CI/CD alignment. Key outcomes include migrating the core codebase from JDK 21 to JDK 25, updating CI/CD pipelines to reference the new Java version, and aligning Docker/Maven configurations with the new runtime. The effort also encompassed stabilizing cloud deployment tests and ensuring branch hygiene after merge. Summary of work: - Upgraded CorfuDB from JDK 21 to JDK 25 and aligned CI/CD pipelines to use Java 25 across workflows, including updates to 8 workflows and documentation. Commits include a full migration (Migrate CorfuDB to JDK 25) and branch synchronization after the merge. - Modernized Docker and Maven configurations for JDK 25 compatibility, upgrading base images to eclipse-temurin:25-jdk-noble and adding necessary --add-opens flags to handle Java module encapsulation; Maven source/target updated to 25 and related flags added in tests and plugins. - Stabilized Docker API interactions and environment: pinned Docker API version to 1.43 across install steps, added DOCKER_API_VERSION where needed, and updated cloud deployment tests to remove deprecated flags. - Improved cloud deployment test reliability: pre-created /tmp/k3dvol to prevent k3d warnings and updated k3s arguments from --no-deploy to --disable, ensuring smoother test runs. - Branch and documentation hygiene: switched corfudb-cloud branch to master after JDK25 merge and updated README with new JDK requirement. No API breakages identified. Business impact: The upgrade enables the project to run on a modern, supported Java runtime with improved security and performance, while maintaining compatibility and stability in CI/CD, deployment pipelines, and tests. The changes reduce upgrade risk and improve developer productivity through more reliable, reproducible builds.
