Mark Struberg commented on CDI-456:
-----------------------------------
to also add what we discussed on IRC on friday:
Bean#getBeanClass() is _only_ defined for 'Managed Beans' at the moment. That
means it is only defined for classes which get scanned at boot time. It is *not* defined
for anything you do via Extensions.
regarding the modularity discussion: yes, using getBeanClass() for that would work for
ManagedBeans which get scanned by the container, but again: it wont work for 3 custom
Bean<T> which are differently configured for each of the 3 WARs. Especially since
getBeanClass() might return null if you strictly follow the spec wording.
So I think we need to
a.) clarify what getBeanClass() shall return for Bean<T> added via Extensions
b.) how modularity works for synthetic beans.
The whole modularity in EAR otoh requires that JavaEE FINALLY properly defines the default
isolation (EAR as 1 classloader + each WAR as child ClassLoader, etc) as standard. If the
EE platform doesn't have a proper modularity specification we have a floating target
and cannot define how CDI should handle it neither.
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.
