[jira] Commented: (HARMONY-217) java.text.BreakIterator.following()
incorrectly calculates the following boundary
[ http://issues.apache.org/jira/browse/HARMONY-217?page=comments#action_12371384 ]
Paulex Yang commented on HARMONY-217:
-------------------------------------
This is a very similar case with JIRA-62, which are both caused by different rules of RI and ICU4J. I believe ICU4J's objective is try best to follow latest Unicode specs, while sometimes they may be different with RI. I will try to study ICU4J document to see if we can customize the rules to comply with RI's behaviour.

> Components: Classlib
> Environment: J9 + Hamony
> Reporter: Anton Avtamonov

> Use the following test case (which pass on RI) to understand the issue:
> import java.text.BreakIterator;
> import junit.framework.TestCase;
> public class BreakIteratorTest extends TestCase {
> private BreakIterator bi;
> protected void setUp() throws Exception {
> bi = BreakIterator.getWordInstance();
> }
> protected void tearDown() throws Exception {
> bi = null;
> }
> public void testFollowing() throws Exception {
> bi.setText("000 111");
> checkWordBounds(2, 0, 3);
> checkWordBounds(4, 3, 6);
> checkWordBounds(7, 6, 9);
> }
> private void checkWordBounds(final int offset,
> final int expectedBeginOffset,
> final int expectedEndOffset) {
> assertEquals(expectedBeginOffset, bi.preceding(offset));
> assertEquals(expectedEndOffset, bi.following(offset));
> }
> }
