This method returns all currencies, including ones to take place in the future (e.g. `XCG`).

I think `XCG=XCG` is also needed for not throwing `MissingResourceException` for `getSymbol()`

I'd not add the future currency, and fix it in the code not to add future currency in available currencies.

test/jdk/java/util/Currency/ValidateISO4217.java line 289:

What is this change for?
