[jboss-jira] [JBoss JIRA] (WFLY-12083) Deployment failure if an explicit bean archive contain a Pojo with @NotNull annotation

[Matěj Novotný (Jira)]

    [ https://issues.jboss.org/browse/WFLY-12083?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13740490#comment-13740490 ] 

Matěj Novotný commented on WFLY-12083:
--------------------------------------

bq. So that would look as an application problem - defining non-proxyable bean but requesting a functionality (validation) that requires a proxy?

Yes, that corresponds to my previous comment.

bq. There's already a configuration option in Weld that causes it to print a warning (instead of failing a deployment) when a final method is being intercepted:

You are right, but this exists because in some cases you can have a class that's perfectly proxyable except for one final method that becomes a blocker. Otherwise the proxy is still usable. Also note that this has roots directly in CDI spec in several forms - as a [lifecycle event method|http://docs.jboss.org/cdi/spec/2.0/cdi-spec.html#process_bean_attributes] or on an [interception factory|http://docs.jboss.org/cdi/spec/2.0/cdi-spec.html#interception_factory].
Here, the story is different. Due to constructor you simply cannot create the proxy *at all*. I would argue that ignoring the class (even with logging) does more harm then actual fail-fast exception for the simple fact that the functionality you tried to apply will be missing altogether.
