Cyberduck (v 3.2 4648) has two windows open, both simple FTP (port 21, one anonymous, one non-anonymous). These connections are -- or should have been -- idle for several DAYS. All I'd done after opening the connections was to list a directory and then hide the application.

The Cyberduck application windows were in the background ("Hide" from Dock menu) and the application had not been selected as a foreground application for several days.

Yet I see cyberduck.app consuming up to 7% CPU -- which matters on a battery-powered laptop -- to do nothing.

Perhaps this is just a bad Java implementation, but perhaps there's something in the Cyberduck application which can be fixed.

I can't really explain this. One possible cause could be Rendezvous/Bonjour activity on the network (services appearing and disappearing). You could try if it makes a difference with Bonjour services discovery disabled for Cyberduck using

defaults write ch.sudo.cyberduck rendezvous.enable false

Thanks for the quick suggestion.
I've added that preference and I'll report back if I still see idle application CPU cycle consumption
