Tim Ellison commented on HARMONY-64: ------------------------------------ This behaviour originates from the ICU provider code, I'll see what they say about it first: http://bugs.icu-project.org/cgi-bin/icu-bugs/incoming?findid=5027 > java.nio.charset.Charset.forName(String name) does not throw > UnsupportedCharsetException if valid 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.
