I have a simple web app doing injection into a JSF managed bean using @EJB. When the managed bean lifecycle and duration is described using the JSF @ManagedBean and @ApplicationScoped I get a "IllegalStateException: WELD-000340 ..." error when loading the welcome page. The only workaround I have seen is to disable implicit CDI usage, but the web app is using CDI, so that is not appropriate.

The problem seems to be a lack of understanding what is going on between the weld and jsf containers. I understand that the JSF @ManagedBean is deprecated in favor of CDI @Named, but it would be nice if we can provide better feedback when @ManagedBean is used along with CDI.

The following git repo provides a complete test application along with the steps to cause the error as well as how to fix it by only using CDI annotations.
