/**
*
* Specifies that a bean is application scoped.
*
*
* While ApplicationScoped must be associated with the built-in application context required by the specification,
* third-party extensions are
* allowed to also associate it with their own context. Behavior described below is only related to the built-in application context.
*
*
*
* The application scope is active:
*
*
*
* - during the service() method of any servlet in the web application, during the doFilter() method of any
* servlet filter and when the container calls any ServletContextListener, HttpSessionListener,
* AsyncListener or ServletRequestListener,
* - during any Java EE web service invocation,
* - during any remote method invocation of any EJB, during any asynchronous method invocation of any EJB, during any call to
* an EJB timeout method and during message delivery to any EJB message-driven bean,
* - when the disposer method or @PreDestroy callback of any bean with any normal scope other than
* @ApplicationScoped is called, and
* - during @PostConstruct callback of any bean.
*
*
*
* 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.
*
*
*
* An event with qualifier @Initialized(ApplicationScoped.class) is fired when the application context is initialized
* and an event with qualifier @Destroyed(ApplicationScoped.class) when the application context is destroyed.
* The event payload is:
*
*
*
* - the ServletContext if the application is a web application deployed to a Servlet container, or
* - any java.lang.Object for other types of application.
