<i18n dev> [12] RFR: 8216546: Support new Japanese era in java.lang.Character for Java SE 11

[naoto.sato at oracle.com]

Hi,

Please review the javadoc fix for the following issue:

https://bugs.openjdk.java.net/browse/JDK-8216546

The CSR and the proposed changeset are located at:

https://bugs.openjdk.java.net/browse/JDK-8217938
http://cr.openjdk.java.net/~naoto/8216546/webrev.00/

This is a forward poring of the fix made in 11u release:
https://hg.openjdk.java.net/jdk-updates/jdk11u/rev/c1e1669edace

The changeset has been modified from the original 11u one, in order to 
mandate the Japanese Era code point in all Java SE 12 implementations.

Naoto
