Worked on the hivemq-community-edition repository to deliver a focused migration of XML binding dependencies from javax.xml.bind to jakarta.xml.bind, aligning the project with Jakarta EE 9+ standards. This effort involved updating dependency versions and import statements across configuration and entity classes, ensuring compatibility with newer Java environments. The work emphasized dependency management and XML processing using Java, consolidating JAXB-related changes to improve build stability and maintainability. By narrowing the scope to XML binding migration, the project reduced runtime risk and streamlined future transitions. No bug fixes were reported during this period, with all engineering efforts dedicated to feature migration and modernization.
