Worked on the eclipse-openj9/openj9 repository to improve Java reflection reliability by addressing a subtle issue in Class.getMethod(). Focused on ensuring that non-public interface methods are correctly rejected, the work involved updating getMethodHelper() to throw NoSuchMethodException when appropriate, aligning with Java access rules. Comprehensive unit tests were added in Java9andUp/GetMethodTests, covering private static, private non-static, and public interface methods to increase test coverage and reduce regression risk. The approach emphasized test-driven development and maintainability, utilizing Java and reflection techniques to enhance API semantics for Java 9+ environments and support downstream users relying on accurate reflection behavior.

Feb 1, 2026February 2026 focused on strengthening Java reflection robustness in eclipse-openj9/openj9. Delivered a fix to Class.getMethod() so non-public interface methods are rejected, aligning behavior with Java access rules. Updated getMethodHelper() to throw NoSuchMethodException in these cases and added comprehensive tests across various access levels (private static, private non-static, and public methods) in Java9andUp/GetMethodTests. The work reduces risk of subtle reflection bugs and improves reliability for downstream users relying on reflection. Impact includes increased test coverage, reduced regression risk for API semantics in Java 9+ environments, and improved maintainability through clear commit messaging. Tech/skills demonstrated: Java reflection, test-driven development, unit testing with Java 9+ features, code review readiness. Commits included: 542e5dad6e7fe620a254c1e3e6dc04dcf1e1cbf8.
