[Bug java/21068] New: String(strBytes, "UTF-16LE"); thorws java.io.UnsupportedEncodingException

[gruni dot ca at gmail dot com]

The constructor String(strBytes, "UTF-16LE"); throws a
UnsupportedEncodingException which is not logical, becasue the Charset is
supported according to Charset.availableCharsets()
TestCase will follow. This is my output

Available Charsets are:
{ISO-8859-1=ISO-8859-1, US-ASCII=US-ASCII, UTF-16=UTF-16, UTF-16BE=UTF-16BE,
UTF-16LE=UTF-16LE, UTF-8=UTF-8}
Exception in thread "main" java.io.UnsupportedEncodingException: UTF-16LE
(java.lang.ClassNotFoundException: gnu.gcj.con
vert.Input_UnicodeLittle not found in
gnu.gcj.runtime.SystemClassLoader{urls=[file:.\], parent=gnu.gcj.runtime.VMClassLo
ader{urls=[core:/], parent=null}})
   at GcjStringTest.main(java.lang.String[])
(E:\2004-development\2005-extraextra\src\GcjStringTest.java)
   at ._main (C:\DOKUME~1\GRUNEW~1\LOKALE~1\Temp\ccM5baaa.i)

And accoring to the APIdocs:

String

public String(byte[] bytes,
              String charsetName)
       throws UnsupportedEncodingException

    Constructs a new String by decoding the specified array of bytes using the
specified charset. The length of the new String is a function of the charset,
and hence may not be equal to the length of the byte array.

    The behavior of this constructor when the given bytes are not valid in the
given charset is unspecified. The CharsetDecoder class should be used when more
control over the decoding process is required.

Parameters:
    bytes - the bytes to be decoded into characters
    charsetName - the name of a supported charset 
Throws:
    UnsupportedEncodingException - If the named charset is not supported
Since:
    JDK1.1 

The charset should be taken out of the Charsets class.

So ya this is a bug in my eyes.

Regards,

Andreas

Created an attachment (id=8665)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=8665&action=view)
Tests the String(strBytes, "UTF-16LE"); which shouldn't return an Exception

This is the testcase which runs without Exception in JDK but throws the
UnsupportedEncodingException when compiled with GCJ.
My system was WinXP with GCJ 4.0 from thisiscool.com

Hope someone can verify this bug.

Then this is most likely the static linking "bug".

In fact yes this is just the static linking problem, if anyone makes GCC make shared libraries for GCC 
that would be useful as nobody as volunteered yet.

The work-around which forces inclusion of the needed class:

import java.io.UnsupportedEncodingException;
import java.nio.charset.Charset;

public class GcjStringTest {

  static {
    gnu.gcj.convert.Input_UnicodeLittle i_UL = new 
gnu.gcj.convert.Input_UnicodeLittle();
  }

  public static void main(String args[]) throws UnsupportedEncodingException{
    System.out.println("Available Charsets are:\n"
        +Charset.availableCharsets().toString());
    byte[] strBytes = {0x12,0x0A,0x14,0xF};
    //Creating String with UTF which is available according to Charsets
    String mine = new String(strBytes, "UTF-16LE");
    //shouldn't recieve Exception
    System.out.println("["+mine+"]");
  }
}

Allright that solved this problem. Unfortunately I can not run the programm
anymore in JDK after adding the static. Is there a way to keep my sources
compatible with JDK and GCJ ?
