Servlet Specs wrote:SRV.10.3.3 Listener Registration
TheWeb container creates an instance of each listener class and registers it for event
notifications prior to the processing of the first request by the application. The Web
container registers the listener instances according to the interfaces they implement
and the order in which they appear in the deployment descriptor. During Web
application execution, listeners are invoked in the order of their registration.
SRV.10.3.4 Notifications At Shutdown
On application shutdown, listeners are notified in reverse order to their declarations
with notifications to session listeners preceeding notifications to context listeners.
Session listeners must be notified of session invalidations prior to context listeners
being notified of application shutdown.
