EXTRA RELEVANT SYSTEM CONFIGURATION :
ext3 filesystem

A DESCRIPTION OF THE PROBLEM :
I have a file containing somewhat weird characters in its name, resulting from grabbing a CD on Windows and storing the files to an SMB-mounted directory on a Linux server. Trying to open the resulting file from Java on the Linux server fails because the result of listFiles on the respective directory causes a FileNotFoundException. The bug seems to have been reported before against 1.3.1 (# 4498715). It seems to be a major interoperability problem.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I used the following C code to create the file:

#include <stdio.h>

int main(char* args[])
{
    FILE* f = fopen("newdir/abc\366def", "w");
    fprintf(f, "nonsense");
    fclose(f);
}

Create a directory "newdir" in the current directory, compile and run the
C program. Then, use the following Java code to reproduce the bug:

import java.io.*;

public class T
{
    public static void main(String[] args)
    {
        try
        {
            File dir = new File("./newdir");
            File[] fa = dir.listFiles();
            for (int i=0; i<fa.length; i++)
            {
                System.out.println(fa[i]);
                for (int j=0; j<fa[i].getPath().length(); j++)
                    System.out.print(", "+(int) fa[i].getPath().charAt(j));
                System.out.println();
            }
            java.io.File f = fa[0];
            java.io.FileInputStream fis = new java.io.FileInputStream(f);
            fis.close();
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }
}
