…ssionMap The method returns a map from a method declaration to expression strings, so the old name misdescribed it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The method checks only that the annotation's expressions parse, not the method body against the annotation. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

A parse error in a contract annotation now names the contract kind, the annotation, and the method, via a new helper parseErrorInContext that is shared with sideEffectsOnlyParseError, instead of prepending an ad-hoc string to a bare flowexpr.parse.error message.

…10-part-2' and 'side-effects-only-2-10-part-7' into side-effects-only-2-10-part-8
Until now, a @SideEffectsOnly annotation was trusted at call sites and only its syntax was checked. The new DisallowedSideEffects scanner verifies a method body -- and a lambda body, against the annotation on the functional interface method -- reporting every side effect that the annotation does not permit. Body checking happens only under -AcheckPurityAnnotations. The new field BaseTypeVisitor.checkPurityAnnotationsOption distinguishes that option from checkPurityAnnotations, which -AsuggestPureMethods and -Ainfer also imply. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
An overriding method, or a method reference, must not permit more side effects than the method it overrides or implements. For an unbound method reference the two methods' parameters do not correspond positionally, so the referenced method's expressions are translated into the frame of the functional interface method before they are compared. Adds PurityKind.SIDE_EFFECTS_ONLY, which only this check consumes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

that Main.java runs this file through a checker that analyzes each call site,
while preserving the surrounding diagnostic explanation.

“Overriding for <`@SideEffectsOnly`>” subsection so it is included in the rendered

In
`@framework/src/main/java/org/checkerframework/common/basetype/DisallowedSideEffects.java`:
- Line 259: Update the implicit super-constructor check in DisallowedSideEffects
to pass a ThisReference for classElt.asType() instead of null to
checkImplicitCall, so receiver-dependent side-effect validation treats the
object under construction as this and permits its fields.
- Around line 905-911: Update visitNewClass to scan anonymous-class instance and
field initializers even when the constructor is considered side-effect-free,
reusing the existing checkSideEffectsOnlyConstructor traversal or equivalent
initializer-checking logic. Preserve the current handling of constructor side
effects while ensuring initializer expressions such as state mutations are
