> Currently if no translation can be found for a given locale then the system generates a lot of WARN messages.
> But for some systems i18n may not be important at all.  And for others, we only really want a warning for one of the languages we care to support, and not for others (they can use the fallback, ie "WEB-INF/translations.po").
> This ticket is to remove the WARN logging in these cases.
> ~~~
> Looking at the implementation, I now see/recall that we have an algorithm (cf ResourceBundles and others) that goes searching for the translation file for a given locale; and if none are found then the fallback translations are used.
> So, the warning is logged if there IS a fallback and it doesn't have a translation for a given msgId.
> Therefore the fix I'm going with is:
> - if the fallback is being used then suppress log WARN messages
> - otherwise preserve current behaviour.
> This means that:
> - systems that do care about i18n requirements for a specific locale (language/country) should include a WEB-INF/translations_XX_yy.po (or just WEB-INF/translations_XX.po)
> - those that don't should simply omit it.
> - there is no need to fully translate the translations.po file
> There was a WARN message if the fallback (transltions.po) file was missing; this is now a simple INFO message instead, the new interpretation being that having no translations.po file is basically the same as having one that has no translations in it.
