Hello,
I just updated to Cyberduck 4.4.4 (Windows 7 64bit) from 4.4.3 and it seems that SFTP login is now broken. I did not check any other protocols though.
When logging in, Cyberduck seems to connect to the server, but when successful, disconnects immediately without switching to the file browser view.

This error appears in the log file (cyberduck.log):

Unfortunately, that does not seem to fix the original problem. Although there's no NullPointerException anymore, I now find the following in the logfile:

[Thread-0] ERROR ch.cyberduck.ui.AbstractController - Error scheduling background task cli.Ch.Cyberduck.Ui.Controller.ConnectionController$ReachabilityAction@1ec0c6 for execution. Task java.util.concurrent.FutureTask@3b60695 rejected from java.util.concurrent.ThreadPoolExecutor@981557[Shutting down, pool size # 1, active threads1, queued tasks # 0, completed tasks2]

There's no stack trace there.

I'm now using Cyberduck 4.5 (14559) from the snapshot channel.

That looks like #7680.
