(Opps, when I opened this the history tab was open rather than comments, and I did not realise that this had already been said)

The Final Release of JSR-299 does not define anything to do with @ApplicationScoped in 6.5.2.

@ApplicationScoped is defined in 6.7.3 and states: "The application context is shared between all servlet requests, web service invocations, EJB remote method invocations,
EJB asynchronous method invocations, EJB timeouts and message deliveries to message-driven beans that execute within
the same application. The application context is destroyed when the application is shut down."

This means that @ApplicationScoped is shared over a whole ear, and is not per war (there may not even be a war in the ear).

> Since @ApplicationScoped currently is defined in 6.5.2 as to be 'like in the Servlet specification' this means that you will get a new instance for every WebApplication (WAR file).
> There is currently no specified CDI scope for providing a single shared instance for a whole EAR.
> We could (ab-)use @Singleton for that, but this is currently not well defined at all.
> Alternatively we could introduce an own new annotation like @EnterpriseScoped or likes.
