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";.
