Daniel Sun reassigned GROOVY-12525:
-----------------------------------
Assignee: Daniel Sun
> STC accepts a call to an isX() or getX() accessor that the property does not
> generate
> -------------------------------------------------------------------------------------
>
> Key: GROOVY-12525
> URL: https://issues.apache.org/jira/browse/GROOVY-12525
> Project: Groovy
> Issue Type: Bug
> Components: Static Type Checker
> Affects Versions: 6.0.0
> Reporter: Scott Murphy Heiberg
> Assignee: Daniel Sun
> Priority: Major
>
> The type checker accepts a call to an accessor method that a property would
> generate, also when the property does not generate it, and the call then
> fails at run time in every mode:
> {code:groovy}
> @groovy.transform.TypeChecked
> class Box {
> boolean flag = true
> boolean getFlag() { flag } // with an explicit getFlag(), no isFlag() is
> generated
> }
> @groovy.transform.TypeChecked
> class C {
> boolean test(Box b) { b.isFlag() }
> }
> new C().test(new Box()) // MissingMethodException: No signature of method:
> isFlag for class: Box
> {code}
> Dynamic Groovy throws the same exception. Under {{@CompileStatic}} the call
> compiles to {{Box.isFlag()}} and fails with {{NoSuchMethodError: 'boolean
> Box.isFlag()'}}. The same happens for {{b.getFlag()}} when {{Box}} declares
> {{isFlag()}} instead, and for {{b.isFlag()}} on a {{Boolean flag}} property,
> which only gets {{getFlag()}}. Without an explicit accessor, a {{boolean}}
> property gets both, and the call works. Seen in 4.0.33, 5.0.8, 6.0.0 and
> master.
> Expected: "Cannot find matching method Box#isFlag()".
