[cdi-dev] [JBoss JIRA] (CDI-625) When exactly are events with @Initialized(X.class) and @Destroyed(X.class) qualifiers fired

[Martin Kouba (JIRA)]

    [ https://issues.jboss.org/browse/CDI-625?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13291603#comment-13291603 ] 

Martin Kouba commented on CDI-625:
----------------------------------

bq. BeforeShutdown extensions are often accessing app scoped beans...
Not legal and should not work.

bq. @AfterDestroyed for the consistency...
Yep, we could introduce {{@AfterDestroyed}} and deprecate {{@Destroyed}}. The event could be fired with both of these qualifiers - the old observers (with {{@Destroyed}}) should still work as they have a subset of the event qualifiers.

bq. and do the same for @Initialized
I don't think it's needed.

> The spec states that {{@Initialized(X.class)}} is fired when a context is initialized and {{@Destroyed(X.class)}} when a context is destroyed (note that for {{@ApplicationScoped}} the wording leaves out the context: _"when the application is destroyed"_). 
> Does it mean that:
> * {{@Initialized(X.class)}} is fired *after the initialization* of a context is finished, i.e. the context is ready?
> * {{@Destroyed(X.class)}} is fired *after the destruction* of a context is finished, i.e. after all the beans are destroyed?
> I'm asking because for {{@Destroyed(X.class)}} it might be useful to perform some cleanup before the context is actually destroyed - see also CDI-601.
> In RI/Weld, the behaivour of {{@Destroyed(ApplicationScoped.class)}} is currently a little bit inconsistent. For webapps and Weld SE, the event is fired before the context is destroyed. But for non-web EE modules (e.g. ejb jar) the event is fired after the context is destroyed.
> I believe this should be more clear.
