> ListFTP uncaught exception
> --------------------------
>
> Key: NIFI-5807
> URL: https://issues.apache.org/jira/browse/NIFI-5807
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.7.1
> Environment: Centos7, OpenJDK Runtime Environment (build
> 1.8.0_181-b13)
> Reporter: Radim Kučera
> Priority: Critical
> Labels: easyfix
>
> Using ListFTP / FetchFTP processors to interact with a slightly bizzare FTP,
> which identifies itself as a "Dopra version: 1.6" but otherwise acts as a
> pretty standard FTP causes following exception.
> By all means this should be at least user-overwritable exception, in a terms
> of "I really don't care what system that is until it works as expected,"
> which is exactly this case.
> As you may expect, it is a vendor stripped down *nix OS Made in China. But
> then again, interacting with it by CLI utilities is fully functional. Is
> there anything that can be fixed in this matter?
