[cdi-dev] [JBoss JIRA] (CDI-686) Could InterceptionFactory accept an interface as type parameter

[Romain Manni-Bucau (JIRA)]

    [ https://issues.jboss.org/browse/CDI-686?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13632441#comment-13632441 ] 

Romain Manni-Bucau commented on CDI-686:
----------------------------------------

Oki, seems OWB does not break for that. Also the spec doesnt prevent it since in the example the type is the interface so this is what ends in the type closure list where inheritance is not relevant. So guess this is a weld bug at the end.

>                     && m.getJavaMember().getParameterCount() == 1) {

>         return interceptionFactory.createInterceptedInstance(new ArrayList<>());
>     }
> {code}
> Parameterized type for injected {{InterceptionFactory}} is an interface {{List<Object>}}, so when calling {{configure()}}, user will work with an {{AnnotatedTypeConfigurator<List<Object>>}} to apply interceptor binding.
> In a standard interceptor usage, interceptor binding on interface are ignored (even if they have {{@Inherited}} annotation), so doing it with {{InterceptionFactory}} could be confusing for some user.
