Checker Framework 3.54.0

Version 3.54.0 (2026-03-02)

User-visible changes

Command-line arguments:

• Added -AinferOutputDirectory.
• Removed long-deprecated -Alint=forbidnonnullarraycomponents.

New command-line argument -Aonelinemsg puts error messages on a single line. This is useful when using a tool that only shows the first line of the error.

The command-line argument -Anomsgtext surrounds the error key with brackets instead of parenthesis. This matches Java error messages.

Implementation details

In AnnotatedTypeFactory, canonicalAnnotation() returns a non-null value.

In AnnotationClassLoader:

• Renamed hasWellDefinedTargetMetaAnnotation() to isTypeQualifierAnnotation(). The method now returns true for annotations bearing @InvisibleQualifier or @SubtypeOf, in addition to the existing @Target(TYPE_USE) check.

In TestDiagnostic:

• Renamed field message to key.
• Added new nullable field message for the full message without the key.

Removed classes and methods that have been deprecated for more than two years.
