> The error has been triggered by using classpath scanning in Spring, but can be reproduced independently.
> The code in the servlet listed below does virtually the same thing as the VFSResourcePatternResolver:
> public class BasicServlet extends HttpServlet{
>     @Override
>     protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
>         ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
>         Enumeration<URL> urls = classLoader.getResources("");
>         StringBuffer buffer = new StringBuffer();
>         while (urls.hasMoreElements()) {
>             URL url = urls.nextElement();
>             VirtualFile file = VFS.getRoot(url);
>             buffer.append(file.getPathName() + "\n");
>         }
>         new PrintWriter(resp.getOutputStream()).println(buffer.toString());
>     }
> }
> Trying to access the servlet results in an error when one URL is converted to a VirtualFile by VFS.getRoot(), and here is the resulting exception. The URL that triggers the error differs if the test is repeated.
