Covariant(out) & generic type kotlin

Question

In Java I can do this:

    interface BaseInterface {}

    interface ExtendsInterface extends BaseInterface {}

    public interface ProblemInterface<E extends BaseInterface> {
        void method(E baseInterface);
    }

    class Main {
        public static void main (String [ ] args) {
            ProblemInterface<ExtendsInterface> problemInterfaceExtendsInterface = new ProblemInterface<ExtendsInterface>() {
                @Override
                public void method(ExtendsInterface baseInterface) {}
            };

             ProblemInterface<? extends BaseInterface> problemInterfaceBaseInterface = problemInterfaceExtendsInterface;
        }
    }

In Kotlin:

    interface BaseInterface

    interface ExtendsInterface: BaseInterface

    interface ProblemInterface<out E : BaseInterface> {
       fun method(baseInterface: E)
    }       

    val problemInterfaceExtendsInterface: ProblemInterface<ExtendsInterface> = object : ProblemInterface<ExtendsInterface> {
        override fun method(baseInterface: ExtendsInterface) {}
    }

    val problemInterfaceBaseInterface: ProblemInterface<BaseInterface> = problemInterfaceExtendsInterface

But the problem is: using covariant (out) but Type parameter occurs in 'in' position

Any idea to solve this? How I can do to works the same code in Java/Kotlin? Thanks
