Vera Petrashkova updated HARMONY-62:
------------------------------------

    Attachment: getSentenceInstance_check.java

It looks like there is the same issues in behavior of  BreakIterator.getSentenceInstance().next() method 
when the used text contains the combinations of the following symbols:
            ".", "!", "?"
In these cases next() returns results which are differ from RI results.

Test getSentenceInstance_check demonstrates this problem.
Output is:
-----------------
."What's the matter?.."
F.I was pretty shaken up!..
F."...I was pretty shaken up..." - he sad.

> Problem details:
> java.text.BreakIterator.getSentenceInstance().next() stops searching for the sentence end, if the new-line character is found in the text and returns the index of the last seen non white space character. Due to j2se 1.4.2 method next() should return the boundary following the current boundary.
> Code for reproducing Test.java:
> import java.text.BreakIterator;
> public class Test {
>     public static void main(String [] args)
>     {
>     	BreakIterator it = BreakIterator.getSentenceInstance();
>     	it.setText("One sentence \n on two lines.");
>     	System.out.println(it.next());
>     }
> }
> Steps to Reproduce:
> 1. Build Harmony (check-out on 2006-01-30) j2se subset as described in README.txt.
> 2. Compile Test.java using BEA 1.4 javac
> > javac -d . Test.java
> 3. Run java using compatible VM (J9)
> > java -showversion Test
> Output:
> java version 1.4.2 (subset)
> (c) Copyright 1991, 2005 The Apache Software Foundation or its licensors, as applicable.
> 14
> Output on BEA 1.4.2 to compare with:
> 28
> Suggested junit test case:
> package org.apache.harmony.tests.java.text;
> import java.text.BreakIterator;
> import java.util.Locale;
> import junit.framework.TestCase;
> public class BreakIteratorTest extends TestCase {
> 	public void test_next() {
> 		// Regression test for HARMONY-30
> 		BreakIterator bi = BreakIterator.getWordInstance(Locale.US);
> 		bi.setText("This is the test, WordInstance");
> 		int n = bi.first();
> 		n = bi.next();
> 		assertEquals("Assert 0: next() returns incorrect value ", 4, n); 
> 		// Regression test for the current issue
> 	   	bi = BreakIterator.getSentenceInstance();
>     		bi.setText("One sentence \n on two lines.");
> 		n = bi.next();
> 		assertEquals("Assert 1: next() returns incorrect value ", 28, n);
> 	}
> }
