>          Key: HARMONY-59
>          URL: http://issues.apache.org/jira/browse/HARMONY-59
>      Project: Harmony
>         Type: Bug
>   Components: Classlib
>     Reporter: tatyana doubtsova
>     Assignee: Tim Ellison
>  Attachments: ChoiceFormatTest.java, ChoiceFormat_patches.txt
>
> Problem details:
> According to j2se 1.4.2, method toPattern() should return a pattern representing the
current state of the message format. However, Harmony throws IndexOutOfBoundsException for
"CHOICE {1,choice}" message format.
> Code for reproducing Test.java:
> import java.text.*;
> 	public class Test {
> 		public static void main(String[] args) {
> 			MessageFormat mf = new MessageFormat("CHOICE {1,choice}");
> 			String ptrn = mf.toPattern();
> 			System.out.println("ptrn = " + ptrn);
> 	    }
> 	}
> 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.
> Exception in thread "main" java.lang.IndexOutOfBoundsException
> 	at java.lang.StringBuffer.setLength(StringBuffer.java:810)
> 	at java.text.ChoiceFormat.toPattern(ChoiceFormat.java:386)
> 	at java.text.MessageFormat.toPattern(MessageFormat.java:802)
> 	at Test.main(Test.java:5)
> Output on BEA 1.4.2 to compare with:
> ptrn = CHOICE {1,choice,}
> Suggested junit test case:
> package org.apache.harmony.tests.java.text;
> import java.text.MessageFormat;
> import java.util.Locale;
> import junit.framework.TestCase;
> public class MessageFormatTest extends TestCase {
>     public static void main(String[] args) {
> 	junit.textui.TestRunner.run(MessageFormatTest.class);
>     }
>     public void test_toPattern() {
>         try {
>             MessageFormat mf = new MessageFormat("CHOICE {1,choice}");
>             String ptrn = mf.toPattern();
>         } catch (Exception e) {
> 	    fail("Assert 0: Unexpected exception " + e);			
>         }
>     }   
> }
