Mark Paluch commented on CDI-456:
---------------------------------

The CDI container would do that. The container would not provide the bean if it's not visible to another module. 

In the end this means {{Bean#getBeanClass()}} is the class of the providing bean (either the class itself or the producer class). 

Introducing a {{Bean.getProxiableType()}} that consistently returns the type which gets created could be a possible solution to inspect the type of the resulting object. Other DI frameworks name it for example {{getObjectType()}}.

> currently Bean#getBeanClass() is defined to return the class of the bean it produces but has one important exception: in case of a producer method or field it must return the class of the owner bean of this method or field.
> Imo this only causes troubles and doesn't add any benefit. 
> * At the time when 'using' the Bean (create and destroy) we always ONLY need the type which is to be created.
> * At the time we create interceptors we ONLY need the type which is to be created;
> * At the time we create the normalscoping proxies we ONLY need the type which is to be created;
> In fact the only time we need the ownerBean is when scanning the methods and fields in it. And for creating we really need the owner-Bean and not it's bean-class!
> In OWB we worked around this by having our own method getReturnType() which consistently returns the type which gets created.
