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:
