Clarify boundaries of the ServletContext event

An event with qualifier @Initialized(ApplicationScoped.class) is fired when the application
context is initialized and an event with qualifier @Destroyed(ApplicationScoped.class) is fired
when the application is destroyed. The event payload is:
• the ServletContext if the application is a web application deployed to a Servlet container, or Conversation context lifecycle
• any java.lang.Object for other types of application.

Unlike dependency injection, the spec does not define any visibility boundaries for events. It could therefore be implied that in an EAR a web application could observe the ServletContext event for a different web application. This obviously does not seem right and the spec should explicitly define the expected behavior.
