Paul King commented on GROOVY-12567:
------------------------------------
This could be expected behavior. AI just flagged it but it seems to have Java
expectations. Just creating the issue until I get time to properly look.
> Dynamic super from an instance method cannot reach a static method of the
> superclass that the subclass hides
> ------------------------------------------------------------------------------------------------------------

> Key: GROOVY-12567
> URL: https://issues.apache.org/jira/browse/GROOVY-12567
> Project: Groovy
> Issue Type: Bug
> Reporter: Paul King
> Priority: Major
>
> When a subclass declares a static method with the same signature as a static
> method of its superclass (hiding it), {{super.m()}} in an instance method of
> the subclass fails in dynamic Groovy and under {{@TypeChecked}}. Under
> {{@CompileStatic}} it calls the superclass's method, as Java does. The same
> call works from a static method of the subclass, and when the subclass
> doesn't hide the method.
> {code:groovy}
> class B {
> static m() { 'B.m' }
> }
> class D extends B {
> static m() { 'D.m' }
> def test() { super.m() }
> }
> assert new D().test() == 'B.m'
> // dynamic and @TypeChecked:
> // MissingMethodException: No signature of method: m for class: B is
> applicable for argument types: () values: []
> {code}
> This affects property access through static accessors too:
> ||{{D}} hides, {{test()}} does||dynamic and
> {{@TypeChecked}}||{{@CompileStatic}}||
> |{{super.m()}}|MissingMethodException|{{B.m}}|
> |{{super.m('a')}}|MissingMethodException|{{B.m}}|
> |{{super.p}} (static {{getP()}})|MissingPropertyException: No such property:
> p for class: D|{{B.p}}|
> |{{super.p = 'a'}} (static {{setP(String)}})|MissingPropertyException: Cannot
> get write-only property: p for class: D|calls {{B.setP}}|
> The last row's message talks about getting a property during a write; 4.0.33
> reported "No such property: p for class: D" there.
> The same calls work in dynamic Groovy when the subclass doesn't hide the
> method, or when {{test()}} is static.
> When the superclass overloads the hidden method, the call doesn't fail; it
> reaches the wrong overload:
> {code:groovy}
> class Base {
> static List log = []
> static void setX(int i) { log << 'int:' + i }
> static void setX(String s) { log << 'str:' + s }
> }
> class D extends Base {
> static void setX(String s) { }
> def test() { super.x = 'a'; log }
> }
> assert new D().test() == ['str:a']
> // dynamic and @TypeChecked: [int:97] ('a' coerced to a char, then to int)
> // with super.x = 'ab': GroovyCastException: Cannot cast object 'ab' with
> class 'java.lang.String' to class 'int'
> // super.setX('a'): MissingMethodException (4.0.33: NullPointerException)
> {code}
> *Expected:* from an instance method, {{super.m()}}, {{super.p}} and {{super.p
> = v}} call the superclass's static method, as they do from a static method
> and under {{@CompileStatic}}, and as {{super.m()}} does in Java.
