RFR: 8369517: Compilation mismatch for equivalent lambda and method reference [v2]

[Vicente Romero]

> Given the following test case:
> 
> 
> import java.util.function.Supplier;
> interface Main {
>     interface X<T> {
>         X<T> self();
>     }
> 
>     static X<?> makeX() {return null;}
> 
>     static <R> X<R> create(Supplier<? extends R> supplier) {return null;}
> 
>     static X<X<?>> methodRef() {
>         return create(Main::makeX).self();
>     }
> 
>     static X<X<?>> lambda() {
>         return create(() -> makeX()).self();
>     }
> }
> 
> 
> javac reports an error for the method reference but not for the lambda. There should be no difference here (error in both cases)
