Java ignores -Dfile.encoding while creating Reader/Writer with default 
encoding. It always uses system default on Solaris 2.7. 

On Solaris 2.6 if LC_CTYPE=ru it also ignores -Dfile.encoding parameter. 

jdk1.1.* works correctly.

This is the test demonstrated the bug:

-------------------------------------
import java.io.*;

public class Test {

  static public void main (String[] args) {
        System.out.println("file.encoding " + 
                System.getProperty("file.encoding"));
        OutputStreamWriter wtr =
                new OutputStreamWriter(new ByteArrayOutputStream());
    	System.out.println("encoding " + wtr.getEncoding());  
  }
}

Incorrectly works when LC_CTYPE=ru
