NullPointerException is thrown at FtpFileObject when processing certain
symbolic link
-------------------------------------------------------------------------------------
Key: VFS-284
URL: https://issues.apache.org/jira/browse/VFS-284
Project: Commons VFS
Issue Type: Bug
Affects Versions: Nightly Builds
Environment: Client is running on Vista Ultimate is accessing FTP
server on Suse Lunux 11.0
Reporter: Kirill Safonov
On the server result of LIST command in "/proc/1" folder contains the symbolic
link with entry "lrwxrwxrwx 1 0 0 0 Oct 18 05:58 cwd"
Since the entry has no "->" part the resulting link destination is kept null
leading to
java.lang.NullPointerException

More robust behavior and detailed error reporting (i.e. special type of
exception) would be very helpful in this case.
