May 2025 performance summary for openrewrite/rewrite focused on strengthening Java analysis, template matching, and member-reference handling. Delivered robust type checking and inference across generics, enhanced template matching for generics and member references, and improved accuracy of variable renaming in member contexts. All work backed by expanded cross-version testing and targeted refactorings, delivering safer automated transformations and greater code stability across Java versions.

April 2025: Delivered key features and fixed critical issues across two repositories, driving safer code generation, stronger type handling, and robust rule enforcement. Resulted in improved business value through safer templates, clearer type semantics, and stronger collection handling in tests.

March 2025: Implemented JavaTemplate Array Matching Support in the openrewrite/rewrite project. Extended JavaTemplate to match primitive and object arrays within method invocations, updated grammar for template parameters to recognize array notation, and added tests verifying array matching behavior. Committed as b26b902afad018fe0b0254c286456c9a2bd8765d (PR #5170). This work improves the reliability of template-based rewrites and reduces manual refactoring.
