> Key: WOOKIE-424
> URL: https://issues.apache.org/jira/browse/WOOKIE-424
> Project: Wookie
> Issue Type: Bug
> Components: Server
> Affects Versions: 0.14.0
> Environment: WildFly 8.0.0.CR1, Undertow web server component
> 1.0.0.Beta31-SNAPSHOT
> Reporter: Darren Jones
>
> 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().
