JDK-8039301 - [ja] Host Locale Provider uses non-translated Calendar field names
Description
SimpleDateformat doesn't display era designator correctly in Japanese locale with the COMPAT provider. Since it works fine in JDK 8 as well as with using the CLDR provider of JDK 11. The issue is a regression bug from JDK 8. //JDK 11 with COMPAT provider $ java -showversion -Djava.locale.providers=COMPAT Test java version "11.0.3" 2019-04-16 LTS Java(TM) SE Runtime Environment 18.9 (build 11.0.3+12-LTS) Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.3+12-LTS, mixed mode) AD19���07���03��� 10���50���01��� //JDK 11 with CLDR provider $ java -showversion -Djava.locale.providers=CLDR Test java version "11.0.3" 2019-04-16 LTS Java(TM) SE Runtime Environment 18.9 (build 11.0.3+12-LTS) Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.3+12-LTS, mixed mode) ������19���07���03��� 10���50���08���

[~neato] Thanks for clearing that up! Confirmed JDK 8u is not affected: $ java -showversion -Duser.language=ja -Djava.locale.providers=JRE Test openjdk version "1.8.0_222-ea" OpenJDK Runtime Environment (build 1.8.0_222-ea-b08) OpenJDK 64-Bit Server VM (build 25.222-b08, mixed mode) ������19���07���09��� 15���36���12��� $ java -showversion -Duser.language=ja -Djava.locale.providers=CLDR Test openjdk version "11.0.3" 2019-04-16 OpenJDK Runtime Environment 18.9 (build 11.0.3+7) OpenJDK 64-Bit Server VM 18.9 (build 11.0.3+7, mixed mode, sharing) ������19���07���09��� 15���38���37��� $ java -showversion -Duser.language=ja -Djava.locale.providers=COMPAT Test openjdk version "11.0.3" 2019-04-16 OpenJDK Runtime Environment 18.9 (build 11.0.3+7) OpenJDK 64-Bit Server VM 18.9 (build 11.0.3+7, mixed mode, sharing) AD19���07���09��� 15���38���47���

This is a regression starting from JDK9, so JDK8 famiies are not affected. [~sgehwolf], you need to run it under Japanese locale, i.e., with -Duser.language=ja.

This seems to affect OpenJDK 11/8 as well: $ java -showversion -Djava.locale.providers=JRE Test openjdk version "1.8.0_222-ea" OpenJDK Runtime Environment (build 1.8.0_222-ea-b08) OpenJDK 64-Bit Server VM (build 25.222-b08, mixed mode) AD19���07���09��� 10���49���20��� $ java -showversion -Djava.locale.providers=CLDR Test openjdk version "11.0.3" 2019-04-16 OpenJDK Runtime Environment 18.9 (build 11.0.3+7) OpenJDK 64-Bit Server VM 18.9 (build 11.0.3+7, mixed mode, sharing) AD19���07���09��� 10���51���31���

With the fix to JDK-8039301, era names are retrieved from locale provider's CalendarNameProvider implementation, instead of DateFormatSymbols.getEras(). COMPAT provider has not been providing Japanese era names for Gregorian calendar through CalendarNameProvider, thus it is falling back to root locale's names.

The issue is reproducible in the mainline JDK.
