> ------------------------------------------
>
> We all know there are issues with the Java EE module architecture. This
> has to be fix at Java EE level and CDI spec will have to follow not the
> other way around.
> Now, regarding this ticket I think Jozef explained more than once why
> {{Bean#getBeanClass()}} should behave this way.  Yet I understand the need
> to get the exact type of a given bean instances. So IMO we should split
> this ticket in 2 :
>
> # Clarify the javadoc and spec description of {{Bean#getBeanClass()}} to
> avoid confusion
> # Add a new method to {{Bean}} returning the exact type of the bean
> instances. something like {{Bean#getInstanceClass()}}

> > 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.
