[Mark Struberg (JIRA)]

    [ https://issues.jboss.org/browse/CDI-456?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12998837#comment-12998837 ] 

Mark Struberg commented on CDI-456:
-----------------------------------

Sorry, seems my explanation was too brief ;)

Imagine you have an EAR with 3 WARs. Each of the WAR files add a Bean with the same class (which is in a shared ear lib), but with different bean attributes and different content.
The beanclass would be the same for all the 3 Bean<T>, but they are still in 3 totally different EE modules.
What means getBeanClass() is not usable to distinct the EE modules.

> 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.
