> SC calls a super trait's static accessor, read as a property in a closure or
> lambda, with the trait instead of the implementing class
> -------------------------------------------------------------------------------------------------------------------------------------
>
> Key: GROOVY-12608
> URL: https://issues.apache.org/jira/browse/GROOVY-12608
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 6.0.0
> Reporter: Scott Murphy Heiberg
> Priority: Major
>
> {code:groovy}
> @groovy.transform.CompileStatic
> trait T { private static int count = 1; static int getCnt() { count } }
> @groovy.transform.CompileStatic
> trait U extends T { String m() { def c = { -> cnt }; c() } }
> class C implements U {}
> assert new C().m() == '1'
> {code}
> Actual: MissingMethodException: No signature of static method: T__count$get
> for class: T is applicable for argument types: () values: []
> The same happens in a lambda, in a static trait method, and for a super
> trait's static property such as static int shared = 3. Writing such a
> property in a closure (cnt = n, cnt++, s = 'y') fails to compile under
> @TypeChecked and @CompileStatic: "Cannot set read-only property: cnt".
> Expected: the assertion passes, as it does in dynamic Groovy and with
> getCnt(). A delegate that has the property still comes first (p.with ... cnt).
> The static compiler calls the static method on the super trait interface,
> which passes the trait itself to the trait helper as the receiver class. The
> type checker looks for setters only on the receiver type, where a static
> interface method is not inherited.
> Seen on master with PR #3115 (GROOVY-12590) applied, which fixes the same
> call outside closures. 6.0.0 fails the same way.
