April 2025 highlights across two OpenRewrite repositories. Key features delivered include migration of tests from Fest 2.x to AssertJ in rewrite-testing-frameworks and the addition of a customizable FQN for Nullable annotations in AnnotateNullableMethods within rewrite-static-analysis. A major bug fix was completed: correct finalization handling for variables declared in try-with-resources to reflect Java's implicit finality, with accompanying tests. Overall impact includes improved test readability, maintainability, and static-analysis accuracy, reducing risk in test and analysis migrations and improving code quality. Technologies demonstrated include Java AST/visitor patterns, test framework migration (Fest to AssertJ), build/configuration updates, and test-driven development across two repos. Business value realized through higher quality tests, more reliable static-analysis, and faster contributor onboarding.
