> We have observed that {{LocalizerRunner}} always gives a LIVE action at the end of localization
process.
> The problem is {{findNextResource()}} can return null even when {{pending}} was not empty
prior to the call. This method removes localized resources from {{pending}}, therefore we
should check the return value, and gives DIE action when it returns null.
