             Summary: Should not switch to root directory when not absolutely 
                 Key: VFS-651
             Project: Commons VFS
          Issue Type: Bug
    Affects Versions: 2.0
            Reporter: Syed Aqeel Ashiq
             Fix For: 2.3

Consider a user X only has read/write access to let's say /sftp and /sftp/abc 
directory on a sftp server. And default directory for user is /sftp
In this case, we have to set userDirIsRoot to false, and thus vfs will try to 
switch to root directory, which will fail due to lack of read permission.

This is the underlying code responsible: 
Boolean userDirIsRoot = 
String workingDirectory = getRootName().getPath();
if (workingDirectory != null && (userDirIsRoot == null || 
!userDirIsRoot.booleanValue())) {
    try {; 
    } catch (SftpException e) {
        throw new 

It purposelessly switches to root directory of filesystem. There is a fare 
use-case that root directory doesn't have read access.

*Possible Fix:* It should not switch to root directory, rather it should switch 
to actual final directory, that would be safest. E.g. if the needed directory 
is '/sftp/abc' then it can switch to that directory in above code, rather than 
switching to root.
