Jozef Hartinger commented on CDI-456:
-------------------------------------

{quote}But just using a Class which can be used in tons of different Beans is not.{quote}

Exactly. If bean type and bean class are the same thing (as this ticket proposes) accesibility resolution won't work well. That's why it is important for producers and often custom beans to distinguish between the type of the bean and the class that defines it!

> 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.
