Default Mappings are broken in the codebehind plugin

When using the codebehind plugin, developers should be able to drop a JSP, freemarker or velocity template into their web-app and codebehind should map it to ActionSupport automagically. Right now, the app server gives an error that an interceptor class cannot be found in default-stack. Attached is a simple app to demonstrate. To reproduce, unzip the app, run mvn jetty:run then try to hit http://localhost:8080/bar/index.action .
