>          Key: HARMONY-79
>          URL: http://issues.apache.org/jira/browse/HARMONY-79
>      Project: Harmony
>         Type: Bug
>   Components: Classlib

> 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

> 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
>         };
>    } 
> }
