> Playing with Wicket 1.5 + Google AppEngine I saw this exception after
> modifying appengine-web.xml:
> WARNING: EXCEPTION
> org.apache.wicket.WicketRuntimeException: There is no application attached to
> current thread Timer-2

> I.e. the asynchronous thread that destroys WicketFilter has no ThreadContext
> thread local and thus this exception.
> I see two problems/solutions:
> 1) HttpSessionDataStore should have noop #destroy() - the Application is
> being destroyed, so all its http sessions will be deleted and there is no
> need to clean the special attribute which stores session's pages
> 2) WicketFilter#destroy() can set/unset the application in ThreadContext, so
> other functionality in all #destroy() methods will have access to the
> Application via Application.get()
> Any objections ?
