------------------------------------------

Tim, I rebuilt Harmony, using revision 368878.
The problem is resolved, thanks.

Output of > java -showversion Test is:

java version 1.4.2 (subset)

PASSED
not the instance of CollationKey

>          Key: HARMONY-28
>          URL: http://issues.apache.org/jira/browse/HARMONY-28
>      Project: Harmony
>         Type: Bug
>   Components: Classlib
>     Reporter: tatyana doubtsova
>     Assignee: Tim Ellison

> Problem details:
> j2se1.4.2 specifies that CollationKey java.text. RuleBasedCollator.getCollationKey(String
source) returns a null CollationKey, if the source String is null.
> Code for reproducing Test.java:
> import java.text.*;
> public class Test {
> 	public static void main(String[] args) {
> 		String source = null;
> 		RuleBasedCollator rbc = null;
> 		String Simple = "< a< b< c< d";
> 		try {
> 			rbc = new RuleBasedCollator(Simple);
> 		} catch (ParseException e) {
> 		}
> 		CollationKey ck = rbc.getCollationKey(source);
> 		System.out.println(ck == null ? "PASSED" : "FAILED");
> 		System.out
> 				.println(ck instanceof CollationKey ? "the instance of CollationKey"
> 						: "not the instance of CollationKey");
> 	}
> }
> Steps to Reproduce:
> 1. Build Harmony-14 j2se subset as described in README.txt.
> 2. Compile Test.java using BEA 1.4 javac
> > javac -d . Test.java
> 2. 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.
> FAILED
> the instance of CollationKey
> Output on BEA 1.4.2 to compare with:
> PASSED
> not the instance of CollationKey
> The suggested junit test case:
> package org.apache.harmony.tests.java.text;
> import java.text.*;
> 	
> import junit.framework.TestCase;
> public class RuleBasedCollatorTest extends TestCase {
>     public static void main(String[] args) {
>         junit.textui.TestRunner.run(RuleBasedCollatorTest.class);
>     }
> 	public void test_getCollationKey() {
> 		String source = null;
> 		RuleBasedCollator rbc = null;
> 		try {
> 			String Simple = "< a< b< c< d";
> 			rbc = new RuleBasedCollator(Simple);
> 		} catch (ParseException e) {
> 			fail("Assert 0: Unexpected format exception " + e);
> 		}
> 		CollationKey ck = rbc.getCollationKey(source);
> 		assertTrue("Assert 1: getCollationKey (null) does not return null", ck == null );	}
> }
