Hi,
I'm trying to sub-class the class gnu.mapping.Symbol from within Kawa.
In the source code, the class has a protected field:

protected String name;

But when I subclass it like this:

(define-simple-class S (gnu.mapping.Symbol)
  ((*init*)
   (invoke-special gnu.mapping.Symbol (("foo":toString):intern)
gnu.mapping.Namespace:EmptyNamespace)
   (set! name (("bar":toString):intern))))

I get the following error:

slot 'name' in gnu.mapping.Symbol not accessible here

What are the rules for accessing protected members in Kawa?
