RFR: 8261006: 'super' qualified method references cannot occur in a static context [v7]

[Vicente Romero]

> Please review this PR, currently javac is accepting code like:
> 
> 
> import java.util.function.Supplier;
> 
> public class MethodReferenceInConstructorInvocation {
>     interface Bar {
>         default String getString() { return ""; }
>     }
> 
>     static class Foo implements Bar {
>         public Foo() {  this(Bar.super::getString);  }
>         public Foo(Supplier<String> sString) {}
>     }
> }
> 
> 
> but the spec states in `15.13 Method Reference Expressions`:
> 
> If a method reference expression has the form super :: [TypeArguments] Identifier
> or TypeName . super :: [TypeArguments] Identifier, it is a compile-time error if
> the expression occurs in a static context (§8.1.3).
> 
> and a constructor invocation is a static context. So method references of this form, qualified by `super`, should be rejected by the compiler if they appear in a static context.
> 
> TIA
