Tim Ellison reassigned HARMONY-64:
----------------------------------
Assign To: Tim Ellison
> java.nio.charset.Charset.forName(String name) does not throw
> UnsupportedCharsetException if invalid name starts with "x-"
> -------------------------------------------------------------------------------------------------------------------------
>
> Key: HARMONY-64
> URL: http://issues.apache.org/jira/browse/HARMONY-64
> Project: Harmony
> Type: Bug
> Components: Classlib
> Reporter: Svetlana Samoilenko
> Assignee: Tim Ellison
>
> According to j2se 1.4.2 specification for Charset forName(String charsetName)
> the method must throw UnsupportedCharsetException "if no support for the
> named charset is available in this instance of the Java virtual machine". The
> method does not throw exception if a unsupported name started with "x-". For
> example, the method throws an exception for not supported name "xyz", but
> does not for "x-yz".
> Code to reproduce:
> import java.nio.charset.*;
> public class test2 {
> public static void main (String[] args) {
> try{
> Charset ch=Charset.forName("x-yz");
> System.out.println("***BAD. UnsupportedCharsetException must be
> thrown instead of creating "+ch);
> } catch (UnsupportedCharsetException e) {
> System.out.println("***OK. Expected UnsupportedCharsetException "
> + e);
> }
> }
> }
> 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)
> ***OK. Expected UnsupportedCharsetException
> java.nio.charset.UnsupportedCharsetException: x-yz
> C:\tmp>C:\harmony\trunk\deploy\jre\bin\java -showversion test2
> (c) Copyright 1991, 2005 The Apache Software Foundation or its licensors, as

> ***BAD. UnsupportedCharsetException must be thrown instead of creating
> Charset[x-yz]
> Suggested junit test case:
> ------------------------ CharsetTest.java
> -------------------------------------------------
> import java.nio.charset.*;
> import junit.framework.*;
> public class CharsetTest extends TestCase {
> public static void main(String[] args) {
> junit.textui.TestRunner.run(CharsetTest.class);
> }
> public void test_forName() {
> try {
> Charset ch=Charset.forName("x-yz");
> fail("Assert 0: UnsupportedCharsetException must be thrown
> instead of creating: " + ch);
> } catch (UnsupportedCharsetException e) {
> }
> }
> }
