<i18n dev> Do developers or end-users create currency.properties?

[Alan Bateman]

As part of preparing for modules in the future [1], we need to look at 
configuration (and other) files in the JDK and see whether such files 
could eventually move to module-private locations.

The Currency classes allows people to override the currency data that 
comes with the JDK by creating the 
file${java.home}/lib/currency.properties. I'm interested to know if this 
is actually used, and if so, is it commonly used. In general then 
creating or configuring files that are located in the JDK images is 
problematic as such changes are lost when switching JDK images. I've 
come across cases where folks have put in sym links into the JDK image 
for time zone data, I'm curious if anyone has come across this for 
currency data too.

Thanks,
