>                 Key: NET-476
>                 URL: https://issues.apache.org/jira/browse/NET-476
>             Project: Commons Net
>          Issue Type: Bug
>          Components: FTP

> 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.
