Clarify serializability requirements for interceptors/decorators
----------------------------------------------------------------

                 Key: CDI-187
                 URL: https://issues.jboss.org/browse/CDI-187
             Project: CDI Specification Issues
          Issue Type: Clarification
          Components: Contexts, Decorators, Interceptors
    Affects Versions: 1.1.EDR1
            Reporter: Jozef Hartinger
             Fix For: 1.1.EDR2


The spec says:

{quote}A managed bean is passivation capable if and only if the bean class is serializable and all interceptors and decorators of
the bean *are serializable*.{quote}

The "interceptors and decorators of the bean *are serializable*" part is problematic. While it is fine to examine the defining class in case of standard interceptors/decorators, the question is: How to find out whether an extension-provided interceptor/decorator in serializable? It does not make sense to check the implementation of the Interceptor/Decorator interfaces nor to examine the class returned by Bean.getBeanClass() as that would break the abstraction.

IMHO, the spec should say that:
{quote}A managed bean is passivation capable if and only if the bean class is serializable and all interceptors and decorators of
the bean are *passivation capable*.{quote}

Where a standard interceptor/decorator would be passivation capable if and only if it implemented the Serializable interface whereas the following section of the spec would handle extension-provided interceptors/decorators.

{quote}A custom implementation of Bean is passivation capable if it implements the interface PassivationCapable. An imple-
mentation of Contextual that is not a bean is passivation capable if it implements both PassivationCapable and Serial-
izable.
{quote}
