> I very rare cases the Freemaker BundleTemplate loader is getting NPE when

> {code}
> This NPE happens when trying to load the resource `templates/` via
> {{Bundle.getResource(..)}}. Even if it appears it does only affect few of the
> installed bundles.
> As the call is only used to check if the folder `templates/` is available in
> a bundle an exception MUST NOT break the whole BundleTemplateLoader
> initialization. Because of that the code needs to be changed to catch this
> NPE and log it on WARN level.
