DecimalFormatTestICU

public class DecimalFormatTestICU extends TestCase
Test for additional features introduced by icu. These tests fail on the RI but succeed on Android 1.0. The features are only accessible through the pattern. Api methods where not introduced to allow direct access of these features. This would have changed the api too much.
