>             Project: Wookie
>          Issue Type: Bug
>          Components: Server
>    Affects Versions: 0.14.0

> In LocalizedResourceFilter, there is code that looks for a localized copy of a resource. Here is an example snippet that gives rise to the exception (around line 185):
>       String filePath = filterConfig.getServletContext().getRealPath(path);
>       if (new File(filePath).exists())
>         return context + path;
> According to the javadoc for ServletContext.getRealPath(), it is allowed to return null if the file does not exist. As my widgets are not localized, this is the case, and a NullPointerException occurs because null is then passed to new File(filePath). 
> I'm not sure why this has not been found before - perhaps other web servers have been returning non-null if a resource does not exist.
> I've fixed it temporarily with a local patch that does an extra null check before calling new File():
>       String filePath = filterConfig.getServletContext().getRealPath(path);
>       if (filePath != null && new File(filePath).exists())
>         return context + path;
> I will attach a patch file since there are 3 places in the file using getRealPath().
