That is right. I confused it with the fact that if you get a ResourceBundle 
for the requested Locale, but that bundle does not contain the requested 
key, the ResourceBundle class will look for the key in the parent bundle 
recursively, up until the default Locale.

So we might be talking about two different scenarios here:
- The primary Locale does not exist, and a secondary Locale should be used
- The requested key does not exist for the primary Locale; the Locale used 
instead cannot be determined

The case I was talking about may be a non-issue, since most localizations 
should include all the keys.
