Worked on the open-telemetry/opentelemetry-java-instrumentation repository to enhance the MainJarPathFinder component, focusing on improving the reliability of JAR path detection during Java agent startup. Addressed issues where command-line flags could appear between the '-jar' argument and the JAR file path, which previously led to startup failures. Updated the command line argument parsing logic in Java to correctly identify the JAR path regardless of flag placement, and developed dedicated tests to validate the new behavior. This work improved the robustness of the instrumentation agent’s startup process, leveraging skills in Java development and command line argument parsing for agent reliability.
