Subject: [jira] Updated: (HARMONY-79) java.util.jar.Attributes.put(Object name, Object value) doesn't throw ClassCastException

[ http://issues.apache.org/jira/browse/HARMONY-79?page=all ]

Nathan Beyer updated HARMONY-79:
--------------------------------

Attachment: Attributes_patch.txt
AttributesTest.java

Wrote a patch for this bug, as well as what would be a similar bug in the
"putAll" method. Also, I attached a test case, which tests these two methods.

For reference, I ran this same test against the following JREs and the test
executed the same: Sun 1.4.2_10, Sun 5.0_5 and BEA 5.0_4_R26.0.

> Key: HARMONY-79
> URL: http://issues.apache.org/jira/browse/HARMONY-79
> Project: Harmony
> Type: Bug
> Components: Classlib
> Reporter: Svetlana Samoilenko
> Attachments: AttributesTest.java, Attributes_patch.txt

> According to the j2se 1.4 and 1.5 specification method
> java.util.jar.Attributes.put throws ClassCastException - if the name is not a
> Attributes.Name or the value is not a String.
> Harmony doesn't throw ClassCastException
> 1) if the name is not a Attributes.Name
> 2) if the value is not a String
> Code to reproduce:
> import java.util.jar.Attributes;
> public class test2 {
> public static void main(String[] args) {
> Attributes att=new Attributes();
> try {
> att.put(new Object(), new String("") );
> } catch ( ClassCastException e) {
> System.out.println("ClassCastException if the name is not a
> Attributes.Name ");
> };
> try {
> att.put(new Attributes.Name("IMPLEMENTATION_VENDOR"), new
> Object());
> } catch ( ClassCastException e) {
> System.out.println("ClassCastException if the value is not a
> String");
> return;
> };
> System.out.println("Wrong. Must be ClassCastException");
> }
> }
> Steps to Reproduce:
> 1. Build Harmony (check-out on 2006-01-30) j2se subset as described in
> README.txt.
> 2. Compile test2.java using BEA 1.4 javac
> > javac -d . test2.java
> 3. Run java using compatible VM (J9)
> > java -showversion test2
> Output:
> C:\tmp>C:\jrockit-j2sdk1.4.2_04\bin\java.exe -showversion test2
> java version "1.4.2_04"
> Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
> BEA WebLogic JRockit(TM) 1.4.2_04 JVM (build
> ari-31788-20040616-1132-win-ia32, Native Threads, GC strategy: parallel)
> ClassCastException if the name is not a Attributes.Name
> ClassCastException if the value is not a String
> C:\tmp>C:\harmony\trunk\deploy\jre\bin\java -showversion test2

> Wrong. Must be ClassCastException
> Siggested fix:
> to change the line 232 in
> archive/src/main/java/java/util/jar/Attributes.java as follows:
> 232 return map.put((Name) key, (String) value);
> Suggested junit test case:
> ------------------------ AttributesTest.java
> -------------------------------------------------
> import java.util.jar.*;
> import junit.framework.*;
> public class AttributesTest extends TestCase {
> public static void main(String[] args) {
> junit.textui.TestRunner.run(AttributesTest.class);
> }
> public void test_put () {
> Attributes att=new Attributes();
> // ClassCastException if the name is not a Attributes.Name
> try {
> att.put(new Object(), new String("") );
> } catch ( ClassCastException e) {
> // expected
> };
> //ClassCastException if the value is not a String
> try {
> att.put(new Attributes.Name("IMPLEMENTATION_VENDOR"), new
> Object());
> } catch ( ClassCastException e) {
> // expected
> };
> }
> }
