java.text.MessageFormat.parse(String): incorrect size of Object array parsed from the string
--------------------------------------------------------------------------------------------

         Key: HARMONY-63
         URL: http://issues.apache.org/jira/browse/HARMONY-63
     Project: Harmony
        Type: Bug
  Components: Classlib  
    Reporter: tatyana doubtsova


Problem details:
Method java.text.MessageFormat.parse(String) returns the array of 10 elements when parsing
string "1,00,00' using pattern "{0,number,#,####}". It should return array of 1 element.

Code for reproducing Test.java:
import java.text.MessageFormat;
import java.util.Locale;

public class Test {
    public static void main(String[] args) {
        try {
            MessageFormat mf = new MessageFormat("{0,number,#,####}", Locale.US);
            Object[] res = mf.parse("1,00,00");
            System.out.println("result's length: " + res.length);
	    for (int i = 0; i < res.length; i++) {
                System.out.println("result is: " + res[0]);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

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.
result's length: 10
result is: 10000
result is: 10000
result is: 10000
result is: 10000
result is: 10000
result is: 10000
result is: 10000
result is: 10000
result is: 10000
result is: 10000

Output on BEA 1.4.2 to compare with:
result's length: 1
result is: 10000

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_parse() {
        try {
            MessageFormat mf = new MessageFormat("{0,number,#,####}", Locale.US);
            Object[] res = mf.parse("1,00,00");
            assertEquals("Assert 0: incorrect size of parsed data ", 1, res.length);
        } catch (Exception e) {
			fail("Assert 0: Unexpected exception " + e);			
        }
    }    
}
