Worked on the apache/kafka repository, focusing on improving test code quality and compliance with project standards. Addressed a Spotless import order violation in the OAuthBearerValidatorCallbackHandlerTest, ensuring the test suite adhered to established formatting guidelines. This targeted fix, implemented in Java with an emphasis on unit testing practices, reduced CI lint failures and contributed to more stable and maintainable test code. By aligning the test file with coding standards, the work reinforced the reliability of automated testing processes and supported ongoing efforts to maintain a clean codebase. The contribution demonstrated attention to detail and commitment to consistent development workflows.
