[cdi-dev] [JBoss JIRA] Commented: (CDI-169) Remove the 'No type variable in event objects' restriction

[Stuart Douglas (JIRA)]

    [ https://issues.jboss.org/browse/CDI-169?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12630655#comment-12630655 ] 

Stuart Douglas commented on CDI-169:
------------------------------------

The way the spec is worded I don't really know if this is the case. At runtime due to type erasure there is not really such a thing as SomeObject<Concrete>, there is only SomeObject, so the actual event object that is fired has a type parameter (and in fact Weld checks this when injecting Event objects and will not allow you to inject Event<SomeType<ConcreteType>>, so it appears I am not the only one that has read it this way). 

At the very least this language should be clarified.

> CDI 10.1 states:
> An event object is an instance of a concrete Java class with no type variables. ... An event type may not contain a type variable.
> Which seems silly considering the container fires events with a type variable at startup. I can't think of any reason why this should be prohibited.
