Good catch, thanks.

This patch causes the appended program to hang with `gij'.
I think the fix is to change _Jv_LayoutVTableMethods to check for
final methods (that don't override a method in the superclass) when
constructing the vtable. I'm testing it now.

class x
{
 public int x1 () { return 3; }
}
public class t extends x
{
 public final int x1() { return 5; }
 public final int x2() { return 7; }
 public static void main(String[] args)
 {
 t z = new t();
 System.out.println(z.x1());
 System.out.println(z.x2());
 }
}
