Replying to raimund:

I have JRE 1.7.0_51. I installed the "Unlimited Strength Java(TM) Cryptography Extension Policy Files" but no success.

There is no JRE installation requirement to run Cyberduck and it is not used.

What is the server DNS name you are trying to connect to?

Unfortunately it's a private FTP server, but I've attached a tcpdump capture of the traffic.

Possibly related to JDK-6956398.
