issue about icu4j_4.2.1

[Deven You]

Hi All,I am doing upgrade work from icu4j_4.0 to the latest icu4j_4.2.1. I
meet a issue about the Korean currency symbol, see icu-text-test_v2.diff in
 HARMONY-6278 https://issues.apache.org/jira/browse/HARMONY-6278. The issue
is that the Korean currency symbol characters between RI and icu's cldr are
different. I think its only a non- bug behavior difference, so we can only
change the currency according to icu4j_4.2.1. How about your opinions?
PS. RI I have used 1.5 and 1.6 to test.
