Mark Struberg commented on CDI-456:
-----------------------------------
jozef, how should that work? The 3 beans are different but have the same beanClass(). So
how should this get implemented?
let's look at what you quoted.

5.1.4
For a custom implementation of the Bean interface defined in Section 11.1, “The Bean
interface”, the container calls getBeanClass() to determine the bean class of the bean
{quote}
So what? Where in this sentence does it state that the 'bean class of the bean'
cannot be null? It neither does define what the 'bean class of the bean' is used
for by the container.

5.1.1.2
For a custom implementation of the Bean interface defined in Section 11.1, “The Bean
interface”, the container calls .. getBeanClass() and getStereotypes() to determine
whether an alternative is selected in a certain bean archive.
{quote}
oh fine, but this is not about Alternatives!
Show me one single line where you read that getBeanClass() must not be null for any custom
bean.
This is just missing from the spec and we should clarify what should happen in this case.
fix Bean#getBeanClass() definition

Key: CDI-456
URL:
https://issues.jboss.org/browse/CDI-456
Project: CDI Specification Issues
Issue Type: Bug
Components: Beans
Reporter: Mark Struberg
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.
