[jira] [Commented] (OWB-1416) Possible misintepretation of spec regarding Unproxyable bean types

["Mark Struberg (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OWB-1416?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17650004#comment-17650004 ] 

Mark Struberg commented on OWB-1416:
------------------------------------

I agree with Romain that a) the spec is not clear and b) our approach is much more safe.
Consider some code accessing the Contextual Reference via Instance<T> or BeanManager.getContextualReference() etc. In that case there is not even an injection point. Does this mean Weld will serve broken CDI beans out to user code? Sounds really wrong to me.

> OWB seems to throw an exception for all unproxyable normal scoped beans. I think that this might be incorrect.
> The [specification|https://docs.jboss.org/cdi/spec/2.0/cdi-spec.html#unproxyable] says the "A bean type must be proxyable if an injection point resolves to a bean", not that all the types of the bean must be proxyable. In other words, as long as the bean is a legal bean, and all injection point resolving to this bean is a proxyable type - no exception should be thrown.
> In the part about [contextual references|https://docs.jboss.org/cdi/spec/2.0/cdi-spec.html#contextual_reference], there is further indications that unproxyable types should be allowed in the set of types for the bean. It's only when you try to get a reference(injected or by bean manager) to an unproxyable type, and the bean must be proxied (normal scoped, intercepted or decorated) an exception should thrown.
> Also, the [Weld user guide suggests introducing an interface as a solution to having an unproxyable bean|https://docs.jboss.org/weld/reference/latest/en-US/html_single/#_client_proxies].
> The current OWB implementation makes a pattern of having an interface and (one or more) implementation class with final fields/methods somewhat difficult :)
