Sebb updated NET-476:
---------------------
Affects Version/s: (was: 3.1)
> FTP parser initialization from invalid line
> -------------------------------------------
>
> Key: NET-476
> URL: https://issues.apache.org/jira/browse/NET-476
> Project: Commons Net
> Issue Type: Bug
> Components: FTP
> Environment: Ubuntu Linux 10.04 amd64, vsftpd 2.2.2
> Reporter: Konrad Garus
>
> After upgrading from 1.4.1 to 3.1, we noticed the FTP client sometimes fails
> to list files. It seems to occur intermittently, possibly when the system is
> under relatively high load and does not respond immediately.
> From stacktraces, it seems like multithreading issues or trying to parse
> system type from reply to another command than SYST:
> {code}
> Caused by: org.apache.commons.net.ftp.parser.ParserInitializationException:
> Unknown parser type: PORT command successful. Consider using PASV.
