Release Note: Support New Japanese Era in java.time.chrono.JapaneseEra - Closed
Description
In order to reduce such future spec change when a new era needs to be added, loosening the JapaneseEra spec would be desired, such that :-

- of(int)/valueOf(String) may accept valid era strings that represent eras beyond the predefined era singletons.
- values() method returns an array that contains beyond known eras.

I am supportive of the proposed changes. I also note that the Javadoc in `of(int)` is poorly worded and missing a full stop after "value 1"
