AspectJ declaremixin with class level annotation not matching

Question

Good morning,

I have defined a custom annotation that I want to use to mark some classes as Auditable

@Target({ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Auditable {

}

And have declared an aspect to handle all classes marked with this annotation. I am using AspectJ with Eclipse

@Aspect
public class AuditableClassAspect extends AbstractAuditableAspect {

@Autowired
private ApplicationContext applicationContext;

// Makes the bean auditable
@DeclareMixin(value="@Auditable *")
public Auditable auditableBeanFactory(Object instance) {
    // Use a bean delegator as a mixin object
    Auditable mixin = applicationContext.getBean(PersistentDelegate.class);
    mixin.setObject(instance);
    return mixin;
}

@Pointcut("get(* (@Auditable *).*) && this(object)")
public void executionGet(Object object) {}

@Pointcut("set(* (@Auditable *).*) && this(object)")
public void executionSet(Object object) {}  
}

Then I have marked a class:

@Auditable
public class Report implements Serializable {

private static final long serialVersionUID = 4746372287860486647L;

private String companyName;
private Date reportingDate;

I am using AspectJ with Spring, and have defined the Aspect in applicationContext.xml

<bean class="com.xxx.aop.AuditableClassAspect" factory-method="aspectOf" />

My issue is that there is no matching happening. The Aspect doesn't "detect" the Report class as an Auditable class.

In eclipse it doesn't show any matching. At run time I have an exception when I am casting my report in an Auditable interface.

Do you have any idea what there is no match?

For information, if in my code I write @DeclareMixin(value="com.xxx.Report") Then I have a matching and the Aspect works. Is there something missing with the annotation?

Thanks

Gilles
