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.
