Checker Framework 4.3.0

Version 4.3.0 (2026-10-01)

User-visible changes

The new Modifiability Checker warns when a program might throw UnsupportedOperationException at run time because it calls a mutating method on a collection that does not support the method.

The new wpi2.sh script does whole-program inference, but requires buildfile edits.

Purity Checker:

• Renamed message keys purity.not.deterministic.X, purity.not.sideeffectfree.X, and purity.not.deterministic.not.sideeffectfree.X to purity.X.
• -AcheckPurityAnnotations issues warnings that it missed previously.

The Checker Framework runs under JDK 27 -- that is, it runs on a version 27 JVM.

The Checker Framework runs noticeably faster, due to performance tuning.

The HTML version of the manual has a new look. In addition to the single-page version, there is a multi-page version.

Changes for type system implementers

JavaParserUtil: moved DEFAULT_LANGUAGE_LEVEL, parseCompilationUnit(), parseStubUnit(), and parseExpression() into new class StaticJavaParserUtil.

Renamed AnnotatedTypes.innerMostType() to innermostComponentType().

Removed the unused method WholeProgramInferenceScenesStorage.updateAnnotationSetInScene().

Methods that used to return (or accept) an IPair now use a record with meaningful component names.
