Worked on the joernio/joern repository to enhance Java platform compatibility by introducing support for Java 13+ and expanding file-system capabilities. Implemented the use of FileSystems.newFileSystem(Path), which required updating build management and configuration to mandate JDK 13 or higher for development, while maintaining Java 11 compatibility for end users. This approach allowed the project to leverage modern Java features without disrupting existing deployments. The work involved close collaboration with other contributors and careful coordination of release strategies. Utilized skills in Java development, Scala, and software architecture to lay the foundation for future file-system enhancements within the codebase.
