@ConstrainedTo(RuntimeType.SERVER)
@Singleton
final class ViewableMessageBodyWriter implements MessageBodyWriter<Viewable> {

    @Inject
    private ServiceLocator serviceLocator;
    @Context
    private Provider<ExtendedUriInfo> extendedUriInfoProvider;

This is Thread-Safe? extendedUriInfoProvider.get() this get UriInfo from
RequestScope?

thanks
