Fixed by this commit. Notice that we take advantage of the Locale.LanguageRange introduced in Java 8.

I've added one more method to expose Accept-Language as List<Locale>. See commit fa5636.

On second thought I've switched to returning the most preferred Locale only. The idea is that if you actually need to examine the full prioritized list then it's best to use Locale#filter. Here is what it looks like actually applied.

I also added a HttpHeaders#setAcceptLanguageAsLocale(Locale) variant.
