Checker Framework 3.31.0

on GitHub

Version 3.31.0 (February 17, 2023)

User-visible changes:

Command-line argument -AshowPrefixInWarningMessages puts the checker name on the first line of each warning and error message.

Signedness Checker changes:

• Cast expressions are not subject to type refinement. When a programmer writes a cast such as (@Signed int) 2, it is not refined to @SignednessGlb and cannot be used in an unsigned context.
• When incompatible arguments are passed to @PolySigned formal parameters, the error is expressed in terms of @SignednessBottom rather than the greatest lower bound of the argument types.

Implementation details:

Moved AnnotationMirrorSet and AnnotationMirrorMap from org.checkerframework.framework.util to org.checkerframework.javacutil.
Changed uses of Set<AnnotationMirror> to AnnotationMirrorSet including in APIs.
Removed methods from AnnotationUtils that are no longer useful:
createAnnotationMap, createAnnotationSet, createUnmodifiableAnnotationSet.

Closed issues:
#5597.
