During installation of war feature method CXFNonSpringServlet.init(ServletConfig sc) is called.
During this call fields 'destinationRegistry' and 'bus' are null.
So, ServletController is created with field destinationRegistry=null after CXFNonSpringServlet.createServletController(ServletConfig servletConfig) call from init method.

After this when I try to access http://localhost:8040/services/ via browser ServletController.invoke(HttpServletRequest request, HttpServletResponse res) is called.
And as destinationRegistry=null, then destinationRegistry.getDestinationForPath(pathInfo, true) call causes NullPointerException.
