Major Description
When using ftps with a secure data channel, camel-ftp cannot recover from a lost connection. This is due to a bug/flaw in the SFTPClient class in commons-net. Once a secure data channel has been established, SFTPClient replaces the connection factory with one that does not provide support for creating "unconnected sockets".
While waiting for a fix from the commons-net team (should they chosse to create one), a work-around in camel-ftp is to always create a new instance of SFTPClient for every connect attempt.
Attached are patches containing an attempt to implement the mentioned work-around. The classes, FtpsOperations, FtpsEndpoint and FtpOperations are involved.
