> If an application uses a custom factory via META-INF/services (such as javax.faces.application.ApplicationFactory), then a purge failure can occur when in *development mode* when an *update occurs to the faces-config.xml.* Additionally, the server must not restart the application (which can occur).

> getPurgeMethod unwraps the factory to get the method, but it then calls the private method on the wrong class ( which doesn't have that purge method)
