Worked on enhancing the openjdk/leyden repository by implementing robust OpenURL handling for bundled macOS applications. Addressed a critical gap where bundled apps failed to process incoming URLs when launched as subprocesses by developing and integrating a native event handler, nativeInstallOpenURLEventHandler, directly into the application lifecycle. This solution ensures consistent and reliable deep-linking behavior, aligning bundled app workflows with those of non-bundled deployments. The work involved close collaboration with teammates through code reviews to maintain project standards. Utilized Java and Objective-C to deliver native application functionality, focusing on macOS development and seamless integration of URL-based workflows for end users.
