[Bug libgcj/28977] New: UTF-16 endianness differs between gcj and Sun JDK

[marcus at better dot se]

This program gives different results with Sun's JDK (Debian sun-java5-jdk
1.5.0-08-1) and gcj:

======== Test.java ========
import java.io.*;

public class Test
{
    public static void main(String[] args) throws java.io.IOException
    {
        OutputStreamWriter o = new OutputStreamWriter(System.out, "UTF-16");
        o.write("Hello!");
        o.flush();
    }
}
===========================

According to Sun's API docs
  http://java.sun.com/j2se/1.5.0/docs/api/java/nio/charset/Charset.html
the UTF-16 encoding is supposed to default to big-endian. This is also
what I get when running with Sun's JVM:

00000000: feff 0048 0065 006c 006c 006f 0021       ...H.e.l.l.o.!

But when I run the same program with gij, I get little-endian output:

00000000: fffe 4800 6500 6c00 6c00 6f00 2100       ..H.e.l.l.o.!.

In both cases I executed the same .class file, compiled with the Sun
JDK.

The system is Debian i386 testing/unstable.

$ gij --version
java version "1.4.2"
gij (GNU libgcj) version 4.1.2 20060729 (prerelease) (Debian 4.1.1-10)
