> The WebExternalResourceStream doesn't check the return value of the
> ServletContext#getResource, which could be null. When the reference is given
> to the Connections#lastModified method this will cause a complaint several
> call layers down stating the URL argument may not be null. The null value is
> a result of the referenced static resource missing, thus the servlet
> container is correctly returning null (as per the Servlet spec).
