Subject [jira] Created: (HARMONY-52) java.io.ByteArrayOutputStream.toString(String) throws IllegalCharsetNameException instead of UnsupportedEncodingException
Date Fri, 27 Jan 2006 09:48:40 GMT
java.io.ByteArrayOutputStream.toString(String) throws IllegalCharsetNameException instead of
UnsupportedEncodingException 
--------------------------------------------------------------------------------------------------------------------------

         Key: HARMONY-52
         URL: http://issues.apache.org/jira/browse/HARMONY-52
     Project: Harmony
        Type: Bug
  Components: Classlib  
    Reporter: Vladimir Ivanov


java.io.ByteArrayOutputStream.toString(String) throws IllegalCharsetNameException instead
of UnsupportedEncodingException 

j2se 1.4.2 and 1.5.0 says, that method java.io.ByteArrayOutputStream.toString(String)
 throws UnsupportedEncodingException, if the named encoding is not supported.

Code to reproduce:
import java.io.*; 
  
public class test29 { 
    public static void main(String[] args)  {
	ByteArrayOutputStream os = new ByteArrayOutputStream(); 
        try { 
	    os.write("ababa".getBytes()); 
            os.toString("this is the name \n of a nonexistent encoding" 
                    + Math.random()); 
        } catch(UnsupportedEncodingException e) { 
            System.out.println("PASSED"); 
        } catch(Exception e) { 
            System.out.println("FAILED: " + e); 
        } 
   } 
}  

Steps to Reproduce: 
1. Build Harmony (check-out on 2006-01-25) j2se subset as described in README.txt. 
2. Compile test29.java using BEA 1.4 javac 
> javac -d . test29.java 
3. Run java using compatible VM (J9) 
> java -showversion test29
