Struts PlugIns are initialized and destroyed by the ActionServlet.init and ActionServlet.destroy methods, so they are (of course) subject to the same potential problems. If you're on a Servlet 2.3 or later container, I would recommend migrating your plugins to use ServletContextListener instead. It's really easy -- just tweak the method signature of the two relevant methods. You have access to the ServletContext for the application (it's in the event parameter), so it's easy to do things like set up application scope caches for your domain tables.
