[weld-dev] annotations on Weld proxy classes

[Emily Jiang]

 It seems Weld proxy has the same annotations as the proxied class. However
this conflicts with Bean validation spec as far as @Valid is concerned.


This section of the bean validation spec is ending up in violation due to
the duplicated annotation:
• One must not mark a method return value for cascaded validation more than
once in a line of a class hierarchy.
In other words, overriding methods on sub types (be it sub
classes/interfaces or interface implementations) cannot mark the return
value for cascaded validation if the return value has already been marked
on the overridden method of the super type or interface.

"The @Valid annotation is used to declare that a cascaded validation of the
given method/constructor parameters or
return values is performed by the Bean Validation provider. "


Here is some debug added to the apache bean validation code that shows
which two classes have the @Valid on the createValidEvent method:

$$$$$$$$$$$$DEBUG clazz = class
org.hibernate.beanvalidation.tck.tests.integration.cdi.executable.CalendarServiceWithCascadingReturnValue$Proxy$_$$_WeldSubclass
method = public
org.hibernate.beanvalidation.tck.tests.integration.cdi.executable.Event
org.hibernate.beanvalidation.tck.tests.integration.cdi.executable.CalendarServiceWithCascadingReturnValue$Proxy$_$$_WeldSubclass.createValidEvent()
$$$$$$$$$$$$DEBUG clazz = class
org.hibernate.beanvalidation.tck.tests.integration.cdi.executable.CalendarServiceWithCascadingReturnValue
method = public
org.hibernate.beanvalidation.tck.tests.integration.cdi.executable.Event
org.hibernate.beanvalidation.tck.tests.integration.cdi.executable.CalendarServiceWithCascadingReturnValue.createValidEvent()
$$$$$$$$$$$$$$$$$DEBUG returnValid = 2 // number of hits having @Valid

If I understand correctly, I think this annotation needs to be treated
differently.
