Ok. CNI behaves just as both OpenJDK and GCJ do on corresponding Java code:

   ArrayList l = new ArrayList();
   Iterator i = l.iterator();
   i.hasNext();

And your example indeed raises IllegalAccessException in both OpenJDK and GCJ:

I am convinced but still unsure how to deal with it. I don't see a way
to translate the direct Java call into the corresponding reflection
part.  I think I settle for the setAccessible() option.
