> The method protected List<URL> getSourceURLs(TilesApplicationContext applicationContext, TilesRequestContextFactory contextFactory) throws an NPE when there are either no resources with tiles definitions in /WEB-INF/**/tiles*.xml, or in classpath*:META-INF/**/tiles*.xml, because applicationContext.getResources() returns null rather than an empty Set in those cases.
> In my web.xml I have:
>     <listener>
>         <listener-class>org.apache.tiles.extras.complete.CompleteAutoloadTilesListener</listener-class>
>     </listener>
> And a few definitions in /WEB-INF/tiles.xml
> If I add a file META-INF/tiles.xml with a bogus definition it works.
