Can I extend, in Java, a Kotlin delegating class?

I'm trying to extend, in Java, a Kotlin delegating class and get the following error:

Cannot inherit from final 'Derived'

See code below.

What I'm trying to do is decorate a method of a class.

Any idea why Kotlin defined Derived as final? Is there a way for Derived to not be final so I can inherit it?

Java:

new Derived(new BaseImpl(10)) { // Getting the error on this line: `Cannot inherit from final 'Derived'`
};

Kotlin:

interface Base {
    fun print()
}

class BaseImpl(val x: Int) : Base {
    override fun print() { print(x) }
}

class Derived(b: Base) : Base by b
