NullPointerException when getting Currency for CurrencyCode.MRU. #63

Open jaredfishy opened 4 years ago

jaredfishy commented 4 years ago

Trying to retrieve the Currency object for MRU throws a NullPointerException.

Code to recreate issue:

Currency currency = CurrencyCode.MRU.getCurrency();

TakahikoKawasaki commented 4 years ago

Currency.getCurrency() is a wrapper for java.util.Currency.getInstance(String). If the getInstance(String) returns null or throws an IllegalArgumentException, Currency.getCurrency() returns null.
