📝 Walkthrough

Walkthrough

A new test file has been added to the Signedness Checker tests directory containing a public class with two methods. The first method demonstrates allowed uses of the @bitpattern annotation, including safe type conversions (Double.doubleToLongBits, Float.floatToIntBits) and bitwise operations that preserve the annotation. The second method contains forbidden operations on @BitPattern-annotated parameters, such as arithmetic operations, compound assignments, unary increments/decrements, and string concatenation, with inline error markers indicating where the checker should report violations.

• Issue Signedness Checker support for bit patterns #3211: The new BitPatternOperations test class directly exercises the @bitpattern qualifier annotation for both allowed and forbidden bitwise/arithmetic operations, supporting the Signedness Checker enhancement for bit-pattern type qualification.

7-23: LGTM!

The allowedUses method provides excellent coverage of valid @BitPattern operations, including type conversions, bitwise operations, and conversions back to primitive types.

---

25-42: LGTM!

The forbiddenUses method provides comprehensive negative test coverage for operations that should be forbidden on @BitPattern values, with appropriate error markers for each violation.

---

1-1: @skip-test is a documented framework feature and does not contradict the PR objective.

The @skip-test directive is a standard Checker Framework mechanism (documented in checker/tests/README.md) used throughout the codebase to temporarily disable test files while still adding them to the repository. Tests are commonly added with @skip-test pending infrastructure changes, dependency readiness, or other valid reasons. The PR successfully adds a test for the @BitPattern qualifier; the directive simply disables it temporarily using the framework's standard practice.

Likely an incorrect or invalid review comment.
