The new java.locale.providers property[1] would be of use here. By default, the JDK does not use the CLDR info shipping in the JDK. There's a JEP for JDK 9 to change that : http://openjdk.java.net/jeps/252 > $ ~/jdk1.8.0_40/bin/java -Djava.locale.providers=CLDR,JRE,SPI TestLocale > shortdateformat=27/5/15 [1] http://docs.oracle.com/javase/8/docs/technotes/guides/intl/enhancements.8.html
