Using Scala type aliases from Java code

Suppose I have type alias defined in scala as

object Foo {
  type Bar = Option[String]
}

It looks like I cannot refer to alias in Java code like that (it simply complains cannot find symbol):

import Foo.*;

public class Cafebabe {
  void bar(Bar x) {
  //...
  }
}

I've tried static import as well.

(More specifically, I have java reflection code which I cannot change that needs to know parameter type and I need to feed Bar alias to it).

I know, I can create wrapper in Scala

class BarWrapper(value: Bar)

but maybe I'm missing some other way?
