[VFS]: getContent().getSize() on hiberfil.sys failed

[anton huber <hu...@hotmail.com>]

Hi!
On WindowsXP exists a special file (hiberfil.sys) for hibernation mode. When 
i try
to determine if this file exists (with java.io.File or VFS) the result is 
FALSE. (Regardless
if it really exists or not). (Seems to be a bug in JDK: 6192331.)
So with java.io.File i can determin the size of this file but with VFS i 
can`t.

Someone knows a workaround to determine the size of this file?



-------------------------------------
Example (Code):

import java.io.File;
import org.apache.commons.vfs.*;

public class Hiberfil {

    public static void main(String[] args) {
        String path = "C:\\hiberfil.sys";
        printFile(path);
        printFileObject(path);
    }

    static void printFile(String path) {
        File f = new File(path);
        System.out.println("File.Exists -> "+f.exists());
        System.out.println("File.Length -> "+f.length());
    }

    static void printFileObject(String path) {
        try {
            FileObject fo = VFS.getManager().resolveFile(path);
            System.out.println("FileObject.Exists -> "+fo.exists());
            System.out.println("FileObject.Content.Size -> 
"+fo.getContent().getSize());
        } catch (FileSystemException e) {
            e.printStackTrace();
        }
    }

}

-------------------------------------
Example (Output):

File.Exists -> false
File.Length -> 469291008
FileObject.Exists -> false
org.apache.commons.vfs.FileSystemException: Could not determine the size of 
"file:///C:/hiberfil.sys" because it is not a file.

None yet. But please add this to
http://issues.apache.org/bugzilla/show_bug.cgi?id=38105 .
This describes a similar problem on UNIX.

Thanks!
