In the Japanese calendar system, the first year of an era should be formatted using the character "元" rather than the numeral "1". The issue arises from a difference in how pattern character lengths are interpreted between CLDR and SimpleDateFormat. The existing `JapaneseEraNameTest` has been updated to cover this fix.
