> If a resource bundle cannot find any of its items them it fails with:
> Caused by: java.lang.NullPointerException

> Both
> org.apache.wicket.resource.bundles.ConcatBundleResource#collectResourceStreams
> and org.apache.wicket.resource.bundles.ConcatBundleResource#getCacheKey
> return null if any of the resources' streams cannot be loaded.
> It would be nice if Wicket logs an error explaining which resource is missing.
