Remko Popma commented on VFS-296:
---------------------------------

We will try to use jstack if the problem occurs again.
Is there a snapshot or beta build somewhere that includes this fix?

> The fix from VFS-216 doesn't help if the ftp server doesn't reply with any messages at all (could happen if it's behind a badly configured firewall for example). What happens is that the client.connect() called from FtpClientFactory hangs, and this line is before timeout parameter is set.
> I suggest the change in the attached patch.
> The scenario can be tested with "netcat -l" instead of a real ftp server.
