> 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.
