Martin Grigorov commented on WICKET-3470:
-----------------------------------------
Cross link the ticket with the discussion in dev@:
http://apache-wicket.1842946.n4.nabble.com/HEADS-UP-A-change-in-web-xml-setup-is-required-td3385721.html.
The outcome is that there is no need to create new ServletContextListener. The
Page serialization don't need to convert to/from SerializedPage when the
Application stops/starts. See the link above for more details.

> and destroy the servlet, and then, ask for serialization. I'm not sure it's a
> wiket bug, tell me if i have to report it against tomcat.
> Here is the trace of the destroy :

> available [native method]
> NativeMethodAccessorImpl.invoke(Object, Object[]) line: not available
> DelegatingMethodAccessorImpl.invoke(Object, Object[]) line: not
> available
> Method.invoke(Object, Object...) line: not available
> Bootstrap.start() line: 289
> Bootstrap.main(String[]) line: 414
> Well at this time, a simple dirty hack is to bypass destroy chain to avoid
> removal of app from managers properties of class PersistentPageManager. But I
> would like to have a real clean solution.
