This only affects jdk19u and below.

JDK-8283277 introduced the currency code SLE associated to Sierra Leone but the currency symbol should be Le.

Actual output:
$ java Test en SL
$ Locale: en_SL, Currency: SLE, Symbol: SLE

Expected output:
$ java Test en SL
$ Locale: en_SL, Currency: SLE, Symbol: Le

After JDK-8296239, the currency symbol for hr_HR should be the euro sign.

Actual output:
$ java Test hr HR
Locale: hr_HR, Currency: EUR, Symbol: EUR

Expected output:
$ java Test hr HR
Locale: hr_HR, Currency: EUR, Symbol: €

Tested with latest jdk17u-dev. This works as expected in later versions with CLDR upgraded to v42 (JDK-8284840).
