Just to add to Naoto's comments.

JDK 8 was the first release to include CLDR locale data (JEP 127). JDK 8 
continued to use the legacy JRE locale data by default but the system 
property could be use to try out CLDR data in advance of the switch to 
using it by default in JDK 9 (JEP 252). From JDK 9 to this day, the 
system property can be used to switch back to the JRE lcoale data 
although this locale data hasn't been maintained for several years.
