[cdi-dev] [JBoss JIRA] (CDI-415) Observer resolution doesn't specify handling of null parameter values

[Martin Kouba (JIRA)]

    [ https://issues.jboss.org/browse/CDI-415?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13285775#comment-13285775 ] 

Martin Kouba commented on CDI-415:
----------------------------------

Weld throws an {{IllegalArgumentException}} which is fine IMHO. Also I don't think this requires spec text change, a javadoc update would be enough.

> There is a gap in chapter 10.2 of the current CDI spec about [observer resolution|http://docs.jboss.org/cdi/spec/1.1/cdi-spec.html#observer_resolution]. It doesn't specify what should happen if an event gets fired using a null value.
