java.nio.charset.Charset.isSupported(String charsetName) does not throw IllegalCharsetNameException for spoiled standard sharset name -------------------------------------------------------------------------------------------------------------------------------------
Key: HARMONY-68 URL: http://issues.apache.org/jira/browse/HARMONY-68 Project: Harmony Type: Bug Components: Classlib Reporter: Svetlana Samoilenko According to j2se 1.4.2 specification for Charset.isSupported(String charsetName) the method must throw IllegalCharsetNameException "if the given charset name is illegal ". "Legal charset name must begin with either a letter or a digit. The test listed below shows that there is no the exception if to insert "-" or "_" symbols before standard sharset name, for example "-UTF-8" or "_US-ASCII". Moreover the method returns "true" in this case. BEA also does not throw the exception but returns "false". Code to reproduce: import java.nio.charset.*; public class test2 { public static void main (String[] args) { // string starts neither a letter nor a digit boolean sup=false; try{ sup=Charset.isSupported("-UTF-8"); System.out.println("***BAD. should be exception; sup="+sup); sup=Charset.isSupported("_US-ASCII"); System.out.println("***BAD. should be exception; sup="+sup); } catch (IllegalCharsetNameException e) { System.out.println("***OK. Expected IllegalCharsetNameException " + 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.
