Worked on stabilizing the opensearch-project/data-prepper repository by upgrading the Armeria dependency to version 1.32.6, directly addressing bugs and removing deprecated annotations. This update also involved replacing deprecated usage of io.micrometer.core.lang to ensure compatibility with Micrometer 1.16.0, thereby reducing runtime risks and aligning with current best practices. The work focused on software maintenance and dependency management using Java, with careful attention to release-note-driven changes and traceability through internal issue tracking. These efforts improved the maintainability and forward compatibility of the codebase, supporting downstream deployments and facilitating collaboration across teams for ongoing ecosystem support.
