Use Scala val as compile-time constant in Java

Question

I would like to use a val in a Scala object as a compile-time constant in Java (specifically in a switch). My code looks like this:

class Scala {} // in case it matters, there is a class of the same name
object Scala {
    val foo = "foo"
}

class Java {
    void switchIt(String on) {
        switch (on) {
            case Scala$.MODULE$.foo: // doesn't compile because foo isn't a field
            case Scala$.MODULE$.foo(): // doesn't compile because foo() isn't a constant
        }
    }
}

I am aware of the following questions but none solves my problem:

• Scala Reflection : why getMethods can return the val members? - explains that a val gets compiled into a method
• Use Scala constants in Java - the answer suggests calling the generated method
• Scala: Compile time constants - suggests using final val to create compile-time constants; however, it is not clear on whether Java sees the result as a compile-time constant and doesn't appear to work in my case

Is there a way to do this?
