Ok, got it by taking a closer look at ob-scala.el. In Babel scala code
isn't compiled and executed, it is run in interactive mode (shell). The
following works as expected (just as an example; you can also do this
without the Fibonacci class).

  #+BEGIN_SRC scala :exports both :results output
    object Fibonacci
    {
      def fib (n : Int) : Int =
      {
        if (n == 1 || n == 2)
          n - 1
        else
          fib (n - 1) + fib (n - 2)
      }
    }
    println (Fibonacci.fib (7))
  #+END_SRC

  #+RESULTS:
  : 8
