"Unconnected sockets not implemented" exception in camel-ftp when using ftps
----------------------------------------------------------------------------

                 Key: CAMEL-2829
                 URL: https://issues.apache.org/activemq/browse/CAMEL-2829
             Project: Apache Camel
          Issue Type: Bug
          Components: camel-ftp
    Affects Versions: 2.4.0
            Reporter: Bengt Rodehav


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.
