Vladimir Strigun commented on HARMONY-52:
-----------------------------------------
Ive found small testcase for the issue:
public static void main(String[] args) throws Exception{
byte[] arr = {'a', 'b', 'c'};
new String(arr, 0, 2, "some charset");
}
The behaviour of this test is the same as original. But charset name "some
charset" is illegal because only following letters are allowed in charset names:
"
The uppercase letters 'A' through 'Z' ('\u0041' through '\u005a'),
The lowercase letters 'a' through 'z' ('\u0061' through '\u007a'),
The digits '0' through '9' ('\u0030' through '\u0039'),
The dash character '-' ('\u002d', HYPHEN-MINUS),
The period character '.' ('\u002e', FULL STOP),
The colon character ':' ('\u003a', COLON), and
The underscore character '_' ('\u005f', LOW LINE).
"
So, if we pass to String(byte[], int, int, String) constructor illegal charset
name, it should anyway throws UnsupportedEncodingException, not
IllegalCharsetNameException .

> 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)
