Checker Framework 3.16.0

on GitHub

Version 3.16.0 (July 13, 2021)

User-visible changes:

You can run the Checker Framework on a JDK 16 JVM. You can pass the --release 16 command-line argument to the compiler. You may need to add additional command-line options, such as --add-opens; see the Checker Framework manual. New syntax, such as records and switch expressions, is not yet supported or type-checked; that will be added in a future release. Thanks to Neil Brown for the JDK 16 support.

The Lock Checker supports a new type, @NewObject, for the result of a constructor invocation.

The -Ainfer command-line argument now outputs purity annotations even if neither -AsuggestPureMethods nor AcheckPurityAnnotations is supplied on the command line.

Implementation details:

• AnnotationFileElementTypes.getDeclAnnotation => getDeclAnnotations
