--- Original description ---
This bug asks to examine the i18n data/properties files under ${java.home}/lib and understand if they are configurations and whether they should be resources files (in resources.jar).

lib/calendars.properties
lib/currency.data
lib/hijrah-config-umalqura.properties

Perhaps there are other files under ${java.home}/lib for i18n not listed above.

The motive for this bug is the modular JDK where we need the flexibility to put anything that is module-private into a module-private location. In this case it would appear that the above files are not a supported interface and so should move to a location that should be read as resources.

As I have separated issues for calendar.properties and hijrah-config-umalqura.properties as distinct issues, this issue intends to deal with currency.data file only. I also modified the title accordingly.
