WebWork2 rocks! I really like it (see my parting post to struts-dev, for grins). Others on my team found the paradigm shift in Tapestry compelling though, and I let the team consensus dominate over my insistence on WW2 (team harmony is better in the long run!).

Here are further details on this issue:
I turned ApplicationLifecycleListener into a ServletContextAttributeListener too, with these methods added:
public void attributeAdded(ServletContextAttributeEvent event) { log.info("event = " + event.getName()); }
public void attributeRemoved(ServletContextAttributeEvent event) { log.info("event = " + event.getName()); }
public void attributeReplaced(ServletContextAttributeEvent event) { log.info("event = " + event.getName()); }
Here is the relevant order of events:

As you can probably tell, I added some additional logging in the contextInitialized/Destroyed message.
So, JRun removes things from application scope before calling the contextDestroyed method. I'll patch this up by doing a comparison and cleanup in attributeRemoved and keep the class implementing ServletContextAttributeListener.
After I get this all working on my end, I'll submit a patch.
