java.text.RuleBasedCollator. getCollationKey (null) does not return null
------------------------------------------------------------------------
Key: HARMONY-28
URL: http://issues.apache.org/jira/browse/HARMONY-28
Project: Harmony
Type: Bug
Components: Classlib
Reporter: tatyana doubtsova
Assigned to: Geir Magnusson Jr
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)

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 ); }
}
