/**
*
* Specifies that a bean is session scoped.
*
*
* While SessionScoped must be associated with the built-in session 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 session context.
*
*
* The session 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
HttpSessionListener, AsyncListener or
* ServletRequestListener.
*
*
*
* The session context is shared between all servlet requests that occur in the same HTTP session.
*
*
* The session context is destroyed:
*
*
*
* - when the HTTPSession times out, after all
HttpSessionListeners have been called, or
* - at the very end of
* any request in which
invalidate() was called, after all filters and ServletRequestListeners have been
* called.
*
*
*
* An event with qualifier @Initialized(SessionScoped.class) is fired when the session context is initialized and an
* event
* with qualifier @Destroyed(SessionScoped.class) when the session context is destroyed. The event payload is
* the HttpSession
