Since upgrading to v1.12, Publish-over-FTP does not work.

Reverting the plugin back to v1.11 has provided a temporary solution.

With v1.12, uploads fail with the following messages:

FTP: Connecting from host [sisyphus.desy.de]
FTP: Connecting with configuration [DESY dCache] ...
FTP: Disconnecting configuration [DESY dCache] ...
ERROR: Exception when publishing, exception message [Failed to parse a file entry returned from the server]
Build step 'Send build artifacts over FTP' changed build result to UNSTABLE

For an example of this, see the console output from build 6951:

https://ci.dcache.org/job/dCache-master/6951/

I captured the network traffic between the FTP server and the Publish-over-FTP plugin using tcpdump.

Here are the TCP streams between the FTP client to the server.

First, here's the command-channel, obviously those starting with a number are replies from the server (I've replaced the username and password with stars):

220 Weak FTP door ready

Here's the data channel, providing the response to the LIST command.
