When more than one interface with the same unqualified name used in the @Serviceannotation

sca-javaci-draft-20070926.doc
Java Component Implementation Specification Version 1.1 draft - Section -
2.1:

The service name computed from @Service annotation is the unqualified name
of the class/interface specified in the annotation.  What happens when
there is more than one interface with the same unqualified name (as given
in the example below) used in the @Service annotation?

package mypkg1;
public interface HelloService {
    String hello1(String msg);
}

package mypkg2;
public interface HelloService {
    String hello2(String msg);
}

@Service(interfaces = {mypkg1.HelloService.class,
mypkg2.HelloService.class})
public HelloServiceImpl implements mypkg1.HelloService, mypkg2.HelloService
{
    public String hello1(String msg) {
        return "hello1 " + msg;
    }
    public String hello2(String msg) {
        return "hello2 " + msg;
    }
}

 Is it an error?  Should the service name include package name of the
interface/class as well?
