Jeroen Douwes updated VFS-573:
------------------------------
    Description: 
We encounter problems when trying to create a file in a hidden directory using 
FTP. The actual bug is that the FileType of the hidden directory is IMAGINARY 
and VFS thinks the directory does not exist.


Before writing the file VFS checks if the parent directory exists using 
AbstractFileObject.getType() (AbstractFileObject:1418).

In FtpFileObject.getInfo(boolean flush) VFS tries to obtain the fileInfo 
(FTPFile) of the directory using FtpFileObject.getChildFile(final String name, 
final boolean flush) on the parent. But since the directory is hidden it 
returns null and the fileInfo is set to UNKNOWN..

FtpFileObject.doGetType() translates the UNKNOWN to FileType.IMAGINARY.

VFS now tries to create the directory which fails because it already exists 
(AbstractFileObject:1424) and creating the OutputStream is aborted with the 
following exception:


Exception in thread "main" org.apache.commons.vfs2.FileSystemException: Could 
not create folder "ftp://localhost/hiddenmap";.
