> Currently javac is accepting code like:
>
>
> class Test {
> void m() {
> var r = (Test & Runnable) () -> System.out.println("Hello, World!");
> }
> }
>
>
> according to: `4.9 Intersection Types` a notional interface can't be induced here as one of the components is a class different from `j.l.Object`
>
> With this fix this code pattern will be rejected with a compiler error
>
> TIA
