> I start a SFTP server like this:
> sshd = SshServer.setUpDefaultServer();
> [...]
> sshd.setFileSystemFactory(new VirtualFileSystemFactory(myRootDir.getCanonicalPath()));
> [...]
> sshd.setSubsystemFactories(Arrays.<NamedFactory<Command>>asList(new SftpSubsystemFactory()));
> I connect to the server with FileZilla.
> Upon connexion, the files in myRooDir correctly appear under the server path '/'. But if I cd to '/c:/Windows/', the files in C:\Windows\ appear, escaping the VFS root.
