[classlib][io] unexpected result for java.io.File.compareTo(File) method
------------------------------------------------------------------------

         Key: HARMONY-829
         URL: http://issues.apache.org/jira/browse/HARMONY-829
     Project: Harmony
        Type: Bug

  Components: Classlib  
    Reporter: Vladimir Ivanov


The Harmony method java.io.File.compareTo(File) returns positive value while RI returns negative.

================= test.java ====================
import java.io.*;

public class test  { 
    public static void main (String[] args) {        
        File f1 = new File("01", "");
        File f2 = new File("0", "");
        System.out.println("f1.getPath() = " + f1.getPath() + ", f2.getPath() = " + f2.getPath());
        System.out.println("f2.compareTo(f1) = " + f2.compareTo(f1) + ", f1.compareTo(f2)
= " + f1.compareTo(f2));
   }
} 
============================================

Output:
C:\tmp\tmp17>C:\jrockit-jdk1.5.0-windows-ia32\bin\java.exe -showversion test

f1.getPath() = 01, f2.getPath() = 0
f2.compareTo(f1) = -1, f1.compareTo(f2) = 1
