Exceptions at Constructor References for inner classes

[bitter_fox]

Hi,
I found two cases which cause of Exceptions at Constructor References for
inner classes:

public class Main
{
    public interface SAM0<R>
    {
        R invoke();
    }

    public interface SAM1<R, A>
    {
        R invoke(A a);
    }

    static
    {
        SAM1<Sub.Inner, Sub> sam = Sub.Inner::new; // NPE
    }
}

public class Sub
{
    public class Inner {}

    static
    {
        Main.SAM1<Inner, Sub> sam = Inner::new; // OK
    }

    {
        Main.SAM0<Inner> sam0 = Inner::new; // OK
        Main.SAM1<Inner, Sub> sam1 = Inner::new; //
InapplicableMethodException
    }
}

These are stack traces:
