> STC accepts access to a private superclass field through a nested subclass
> under @TypeChecked, which fails at run time
> ----------------------------------------------------------------------------------------------------------------------
>
> Key: GROOVY-12610
> URL: https://issues.apache.org/jira/browse/GROOVY-12610
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 4.0.33, 5.0.8, 6.0.0
> Reporter: Scott Murphy Heiberg
> Priority: Major
>
> {code:groovy}
> class Base {
> private String z = 'x'
> @groovy.transform.TypeChecked
> static class Sub extends Base {
> def m() { this.z } // also: z, super.z, closures, lambdas, writes,
> that.z
> }
> }
> new Base.Sub().m()
> {code}
> Actual: the code compiles, then fails with MissingPropertyException: No such
> property: z for class: Base$Sub. Dynamic Groovy fails the same way.
> Expected: under @TypeChecked, a compile error "No such property: z for class:
> Base$Sub", as already reported when Base and Sub are both nested in another
> class. @CompileStatic keeps accepting the code, because it accesses the field
> directly from a nest-mate.
> Cause: the type checker uses the nest-mate accessibility rule of static
> compilation for @TypeChecked code too. Type-checked code is dispatched
> dynamically, and the metaclass of a subclass does not list a private field of
> its superclass.
> Seen in 4.0.33, 5.0.8 and 6.0.0.
