Checker Framework 2.9.0

on GitHub

Version 2.9.0, July 3, 2019

Renamed the Signedness Checker's @Constant annotation to @SignednessGlb.
Introduced an alias, @SignedPositive, for use by programmers.

Annotated the first argument of Opt.get and Opt.orElseThrow as @NonNull.

Removed meta-annotation @ImplicitFor:

• Use the new meta-annotation @QualifierForLiteral to replace @ImplicitFor(literals, stringpatterns).
• Use the meta-annotation @DefaultFor to replace @ImplicitFor(typeKinds, types).
• Use the new meta-annotation @UpperBoundFor to specify a qualifier upper bound for certain types.
• You can completely remove @ImplicitFor(typeNames = Void.class, literals = LiteralKind.NULL) on bottom qualifiers. @DefaultFor(types = Void.class) and @QualifierForLiterals(literals = LiteralKind.NULL) are added to the bottom qualifier by default.

Added @DefaultQualifierOnUse and @NoDefaultQualifierOnUse type declaration annotations

New/changed error message keys:

• initialization.static.fields.uninitialized for uninitialized static fields
• unary.increment.type.incompatible and unary.decrement.type.incompatible
  replace some occurrences of compound.assignment.type.incompatible

Implementation details:

• Renamed QualifierPolymorphism#annotate methods to resolve
• Renamed ImplicitsTreeAnnotator to LiteralTreeAnnotator
• Renamed ImplicitsTypeAnnotator to DefaultForTypeAnnotator
• Removed TypeUseLocation.TYPE_DECLARATION
• Removed InheritedFromClassAnnotator, replace with DefaultQualifierForUseTypeAnnotator
• Rename TreeUtils.isSuperCall and TreeUtils.isThisCall to isSuperConstructorCall and isThisConstructorCall
