Worked on the adoptium/aqa-tests repository to enhance test stability for OpenJDK11 on linux-arm systems. Focused on configuration management and test management by updating the ProblemList to exclude a problematic runtime test, thereby reducing flaky runs and improving the reliability of continuous integration pipelines. Utilized text-based configuration files to ensure data consistency and maintainability, including reorganizing the ProblemList_openjdk11.txt into alphabetical order. This targeted bug fix enabled more predictable test outcomes and faster feedback for developers. The work demonstrated attention to detail in test exclusion and configuration management, contributing to cleaner test data and a more stable testing environment.
