Peter Ertl resolved WICKET-3011.
--------------------------------
Resolution: Invalid
The shutdown order is "fixed" in the latest version of jetty, according to Greg
Wilkins, the father of jetty.
see http://jira.codehaus.org/browse/JETTY-1266:
> OK, I'm kind of convinced that it's a good idea.
> But I have to work out how to do it nicely in the code. In Jetty we have
> nested handlers, with Context->Session->Security->Servlet,
> so that is why filters (as part of the Servlet Handler) are destroyed before
> sessions - it's the natural nesting of the stop method.
>
> Turns out the code change is trivial... and better yet, not jetty test cases
> failed as a result.
> So committed to jetty-7 trunk r2286
>
So there's no reason to mess around with this but recommend people to upgrade
to to jetty 7.1.7 (or 7.2) which should be out soon.

> when using jetty 7, creating at least one http session and then shutting down
> the web app context of the wicket web application the following happens:
> - (1) jetty destroys the wicket filter by calling
> javax.servlet.Filter#destroy()
> - (2) the thread local mapping application key ---> application will be
> purged
> - (3) jetty calls
> org.apache.wicket.session.SessionBindingListener.valueUnbound for the
> expiring session:
> --code--
> public void valueUnbound(final HttpSessionBindingEvent evt)
> {
> if (log.isDebugEnabled())
> {
> log.debug("Session unbound: " + sessionId);
> }
> ///////////////
> ////////////// THE APPLICATION WILL BE NULL SINCE THE
> ////////////// WICKET FILTER ALREADY REMOVED IT
> ///////////////
> Application application =
> Application.get(applicationKey);
>
> if (application == null)
> {
> ///////////////
> /////////////// YOU WILL SEE THE MESSAGE BELOW
> ///////////////
> log.error("Wicket application with name '" +
> applicationKey + "' not found.");
> return;
> }
> ///////////////
> /////////////// NO LISTENERS WILL BE INVOKED
> ///////////////
> ISessionStore sessionStore =
> application.getSessionStore();
> if (sessionStore != null)
> {
> for (UnboundListener listener :
> sessionStore.getUnboundListener())
> {
> listener.sessionUnbound(sessionId);
> }
> }
> }
> --code--
> Can somebody confirm the order jetty executes the handlers is right / wrong?
> In case it's wrong we should file a ticket at jetty.
> In case it's right we should fix that issue in wicket.
> Not fixing this incorrect behavior will mean the session unbound listeners
> will not be called reliably.
