{quote}You think it is here for modules?{quote}
Not only for modules but yes. It's referenced quite a lot in Section 5.1. Modularity

{quote}Well in a war no big deal{quote}
How?

{quote} in an ear the container does it since it deploys it{quote}
How? You have an extension that registered a custom bean. What information do you use to
infer where the bean belongs? The same module as the extension's? Some type from
Bean.getTypes()? Or something else?

 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.
