[weld-issues] [JBoss JIRA] Commented: (WELD-491) Warn if CDI annotations are placed on classes that are not managed beans

[Nicklas Karlsson (JIRA)]

    [ https://jira.jboss.org/jira/browse/WELD-491?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12526286#action_12526286 ] 

Nicklas Karlsson commented on WELD-491:
---------------------------------------

Is there something in the spec that says we can't have servlet listeners as managed beans? One could think of usecases when you would like to register servlet listener instances (Servlet 3) that are managed beans (interceptors, alternatives etc).
