[threeten-dev] SimpleDateFormat and DateTimeFormatter produce different result for JapaneseDate

[Masayoshi Okutsu]

Hi,

This one isn't reproducible with b87. Both SimpleDateFormat and 
DateTimeFormatter produce the era name in Japanese.

BTW, SimpleDateFormat and DateTimeFormatter patterns aren't compatible. 
DateTimeFormatter doesn't support the text presentation of the first 
year of an era, for example.

Thanks,
Masayoshi
