array.clone() doesn't work

[Remi Forax]

Tracking a bug in the backport, I've discovered that I forget to have a 
special case for Object[].clone(),
the backport currently reports that the method is protected 
(Object.clone is protected) thus not accessible.

The latest jdk8 binary also have some trouble with array.clone too.

public class JDKBug {
   public static void main(String[] args) throws Throwable {
     MethodHandles.lookup().findVirtual(Object[].class, "clone", 
MethodType.methodType(Object.class));
   }
}

Exception in thread "main" java.lang.InternalError
