Subject [drlvm][kernel] getGenericSuperclass failure
Date Tue, 22 Apr 2008 09:46:21 GMT
Thanks to Dims for this simple test [1].  Any DRLVM person see what is 
happening here?


   public class Harmony5752 {
       public final class A extends B<String, byte[]> {
       }

       public abstract class B<V, T> {
       }

       public static void main(String[] args) throws Exception {
           System.out.println(A.class.getGenericSuperclass());
       }
   }


On the RI it prints out:
   "Harmony5752.Harmony5752$B<java.lang.String, byte[]>"

On Harmony with IBM VME it prints out:
   "null"

On Harmony with DRLVM it fails with:
Uncaught exception in main:
