We have decided to defer this fix until the next official release of ICU4JNI

Hello Tim,
Agree. We can defer this issue to icu4jni's next release. And yes, I
will have a look at icu4j 3.4.2. :-)

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

Not a problem. So do people think we should take HEAD from ICU4JNI to
fix this problem, or wait for the next ICU release?
Unless this bug is hurting somebody I'm inclined to defer it, since I'm
assuming HEAD is the code du jour, and we probably only want the stable
stuff! (no slur on the good folk at ICU, obviously)

> 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) {
> }
>}
> }
