It would be great if you could post the stacktrace to see where it is 
thrown.
Is it really listFiles() which throws the excpetion?

On what operating system do the ftp-server run?
I have tried your example and it worked fine with my linux host.

If one of the FTPFile Entries are null and this cause your 
NullPointerException, than this is due to a bug in UnixFtpEntryParser.
Currently files with permissions other than "rwx" cause the FTPClient to 
return null values.

I already filed a bug about this 
(http://issues.apache.org/bugzilla/show_bug.cgi?id=27858)

As a workaround you could copy UnixFtpEntryParser and change the regexp
+ "(((r|-)(w|-)(x|-))((r|-)(w|-)(x|-))((r|-)(w|-)(x|-)))\\s+"
to
+ 
"(((r|-)(w|-)(x|X|s|S|t|-))((r|-)(w|-)(x|X|s|S|t|-))((r|-)(w|-)(x|X|s|S|t|-)))\\s+"

You have to pass this parser to listFiles then.

Ciao,
Mario
