PageableArgumentResolver unable to apply PageableDefaults.

Hi,
I have a legacy Spring MVC App, for which I wrote this controller: Sorry if this is the wrong forum for this.

@Controller
@RequestMapping("/report")
public class ReportResource
{
@Inject private ReportService service;
@RequestMapping(method = RequestMethod.GET, produces = "application/hal+json" )
ResponseEntity getReport(@PageableDefault(size = 100, page = 0) Pageable pageable)
{
System.out.println("size = " + pageable.getPageSize());
return new ResponseEntity<>(HttpStatus.OK);
}
}

when I launch my server I can see in the debugger that the method:
getDefaultFromAnnotationOrFallback() at the PageableArgumentResolver
returns false while evaluating if (annotation instanceof PageableDefaults)
because the annotation handler points to a Proxy class instead of PageableDefaults.

what am I doing wrong?
thanks in advance!

  <import resource="classpath:META-INF/spring/app-context.xml"/>
  <context:component-scan base-package="com.precor.reportingApi.rest"/>
  <bean class="org.springframework.data.web.config.HateoasAwareSpringDataWebConfiguration" />

 <mvc:annotation-driven>
    <mvc:argument-resolvers>
      <bean  class="org.springframework.data.web.PageableArgumentResolver"/>
    </mvc:argument-resolvers>
  </mvc:annotation-driven>
</beans>

Start with PageableArgumentResolver#getDefaultFromAnnotationOrFallback and the controller's @PageableDefault parameter. Then inspect the mvc:argument-resolvers configuration and the annotation type observed by the resolver. Done means determining why the configured resolver receives a proxy rather than the expected pageable-default annotation and documenting or correcting the supported setup.
