October 2025 performance recap for adoptium/aqa-tests: Implemented cross-platform enhancements and stability improvements that broaden test coverage and reduce flaky results. The changes focus on ZOS platform support and stable GC tuning for J9 system tests, delivered through targeted Groovy/Jenkins automation and cache cleanups.

In Aug 2025, delivered automation to clean up test libraries and standardized build environment dependencies in adoptium/aqa-tests, enhancing cross-platform reliability and reproducibility of test runs. The changes reduce manual maintenance and shorten onboarding time for new contributors.

For 2025-06, delivered feature flag-based enablement and test-suite expansions for the AQA Tests repository, focusing on safer rollout and broader validation of Renaissance components.

May 2025 highlights: Implemented Renaissance Test Coverage Expansion for adoptium/aqa-tests by enabling Renaissance tests for versions 18+ and activating the renaissance-movie-lens test on s390_linux. This broadens validation for newer software versions and enhances cross-architecture coverage, improving release confidence and customer value. Commit 647469a070379125e22fc7ec21cc02bc628b2c78 documents the change as 'Enabled the renaissance tests for 18+ versions (#6270)'.

March 2025 monthly summary for adoptium/aqa-tests focused on reliability and stability improvements through dependency management. Key feature work in this period was not feature development but a targeted bug fix that removed a CI blocker by upgrading a third-party dependency. No code changes were required beyond the dependency upgrade.

February 2025: Consolidated Windows-specific test automation stability across two repositories by migrating from deprecated WMIC usage to PowerShell-based solutions. In eclipse-openj9/openj9, replaced the deprecated WMIC approach with a PowerShell command to retrieve Java process IDs, preserving getPid functionality in runtime automation tests. In adoptium/aqa-tests, replaced WMIC-based memory retrieval with PowerShell Get-CimInstance to compute total physical memory in MB, ensuring continued test functionality and future support.
