[classlib][luni]util:currency.getInstance does not throw IllegalArgumentException
---------------------------------------------------------------------------------

                 Key: HARMONY-6654
                 URL: https://issues.apache.org/jira/browse/HARMONY-6654
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Jin Yang


executing this code 
   Currency c = Currency.getInstance("ABC");
   System.out.prvintln(c);

 we get ABC as output in HS where as on SUN ri we get IllegalArgumentException because ABC is not a supported ISO 4217 code.

In our current design for getInstance(String currencyCode), we do not check the input currencyCode. If we use icu to check, it still doesn't work. ICU just checks if the input is a 3-letter alpha code while not to check if the input is a supported ISO 4217 code. So for ICU, "ABC" is also a valid input.

I think there 2 two ways to fix it:
1. ask ICU to check the input.
2. maintain a ISO 4217 code list in our implementation and to check the input by ourself.
