  |[sca-j] NEW ISSUE: Service name conflict between @Service and @WebService                                                                         |

Target: CAA Spec CD04 and JCI Spec CD2

Description: The CAA spec defines rules in section 10.28 for the name of a
service exposed by an implementation with an @Service annotation.  Section
11.1 of the spec defines rules for the service name when an implementation
class or an interface is annotated with @WebService.  Section 8.2.1 of the
JCI spec also has rules for the service name in the presence of an
@WebService annotation.

These rules can be in conflict if both @Service and @WebServices
annotations are present.  For example:

@Service(ServiceWithName.class)
public class serviceWithNameImpl implements ServiceWithName {
        ...
}

and

@WebService(name="AnnotationName")
@Remotable
public interface ServiceWithName {
        ...
}

The @Service annotation would imply that the service name of a component
using serviceWithNameImpl as an implementation would be ServiceWithName but
@WebService annotation requires the service name to be AnnotationName.

Proposal:  We either need to require an error to be raised or define the
precedence of the two annotations.
