Description
When doing Net::FTP.list command, I get an IOError exception after the last line of the list has been processed. Occurs under jirb or jruby
frag.rb:
require 'net/ftp'
ftp = Net::FTP.open('ftpmvs','uid','pw')
ftp.debug_mode = true
ftp.list() {|line| p line}
ftp.close

| JRUBY-1119 | FTP.nlst error !!! |

I set up vsftpd on my linux laptop and was able to duplicate this error when FTP'ing to localhsot as an anonymous user, so it is not related to the corporate firewall/proxy environment or the fact that i was FTp'ing to unusual hosts (like an IBM mainframe)
