Tim Ellison reassigned HARMONY-65:
----------------------------------
Assign To: Tim Ellison
> java.text.MessageFormat.applyPattern(String pattern) and two MessageFormat
> constructors fail to detect unmatched braces in the pattern
> --------------------------------------------------------------------------------------------------------------------------------------
>
> Key: HARMONY-65
> URL: http://issues.apache.org/jira/browse/HARMONY-65
> Project: Harmony
> Type: Bug
> Components: Classlib
> Reporter: tatyana doubtsova
> Assignee: Tim Ellison
>
> Problem details:
> According to j2se 1.4.2 constructors MessageFormat(String pattern),
> MessageFormat(String pattern, Locale) and method applyPattern(String pattern)
> should throw IllegalArgumantException, if the pattern is invalid. Harmony
> implementation doesn't throw IAE, when there are unmatched braces in the
> pattern
> Code for reproducing Test.java:
> import java.text.*;
> import java.util.Locale;
> public class Test {
> public static void main(String[] args) throws Exception {
> MessageFormat mf = new MessageFormat("{0,number,integer}");
> String badpattern = "{0,number,#";
> try{
> mf.applyPattern(badpattern);
> System.out.println("pattern = " + mf.toPattern());
> System.out.println("applyPattern(String) FAILED to detect
> invalid pattern");
> } catch (IllegalArgumentException e) {
> System.out.println(e.getMessage());
> System.out.println("applyPattern(String) PASSED");
> System.out.println(e.getMessage());
> }
> try {
> mf = new MessageFormat("{0,number,integer");
> System.out.println("pattern = " + mf.toPattern());
> System.out.println("MessageFormat(String) FAILED to detect
> invalid pattern");
> } catch (IllegalArgumentException e) {
> System.out.println(e.getMessage());
> System.out.println("MessageFormat(String) PASSED");
> }
> try {
> mf = new MessageFormat("{0,number,integer", Locale.US);
> System.out.println("pattern = " + mf.toPattern());
> System.out.println("MessageFormat(String, Locale) FAILED to
> detect invalid pattern");
> } catch (IllegalArgumentException e) {
> System.out.println(e.getMessage());
> System.out.println("MessageFormat(String, Locale) PASSED");
> }
> }
> }
> 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.
> pattern = {0,number,#}
> applyPattern(String) FAILED to detect invalid pattern
> pattern = {0,number,integer#}
> MessageFormat(String) FAILED to detect invalid pattern
> pattern = {0,number,integer#}
> MessageFormat(String, Locale) FAILED to detect invalid pattern
> Output on BEA 1.4.2 to compare with:
> Unmatched braces in the pattern.
> applyPattern(String) PASSED
> Unmatched braces in the pattern.
> Unmatched braces in the pattern.
> MessageFormat(String) PASSED
> Unmatched braces in the pattern.
> MessageFormat(String, Locale) PASSED
> 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_MessageFormatString() {
> try {
> MessageFormat mf = new MessageFormat("{0,number,integer");
> fail("Assert 0: Failed to detect unmatched brackets.");
>
> } catch (IllegalArgumentException e) {
> }
> }
>
> public void test_MessageFormatStringLocale() {
> try {
> MessageFormat mf = new MessageFormat("{0,number,integer",
> Locale.US);
> fail("Assert 0: Failed to detect unmatched brackets.");
>
> } catch (IllegalArgumentException e) {
> }
> }
> public void test_applyPatternString() {
> MessageFormat mf = new MessageFormat("{0,number,integer}");
> String badpattern = "{0,number,#";
> try{
> mf.applyPattern(badpattern);
> fail("Assert 0: Failed to detect unmatched brackets.");
>
> } catch (IllegalArgumentException e) {
