Bug in MethodHandles.convertArguments

[Rémi Forax]

For me it's a new bug.
I have checked with jdk7 latest binaries
I will check with the mlvm repository sources when I will be at my 
office with a fast connection.

public class ConvertBug {
   public static Object foo(Object o1, Object o2) {
     return null;
   }

   public static void main(String[] args) {
     MethodHandle mh = 
MethodHandles.lookup().findStatic(ConvertBug.class, "foo",
         MethodType.methodType( Object.class, Object.class, Object.class));
     mh = MethodHandles.convertArguments(mh,
         MethodType.methodType(Object.class, int.class, Object.class));
     System.out.println("print mh "+mh);
   }
}

Exception in thread "main" java.lang.IllegalArgumentException: 
mismatched parameter count

and I don't see any workaround :(
