Problem with SFTP endpoint in FSW 6.0

Issue

We are using Switchyard from where we are trying to connect to a sftp server using camel's sftp endpoint. The sftp host name used is: sftp.myftpserver.com

The writing of the file fails with the following trace:

03-09-2015 08:18:46,047 WARN  (org.apache.camel.processor.DefaultErrorHandler) [Camel (camel-157) thread #296 - file:///integrations/in/pending] Failed delivery for (MessageId: ...). On delivery attempt: 1 caught: org.switchyard.HandlerException: org.apache.camel.FailedToCreateProducerException: Failed to create Producer for endpoint: Endpoint[sftp://ftpuser:******@sftp.myftpserver.com:22/Test/?autoCreate=false&binary=true&bufferSize=131072&connectTimeout=10000&consumer.bridgeErrorHandler=true&disconnect=true&fileExist=Fail&fileName=%24%7Bheaders.outFileName%7D&passiveMode=false&recursive=false&stepwise=false&tempFileName=%24%7Bfile%3Aname%7D.tmp&throwExceptionOnConnectFailed=true]. Reason: java.lang.IllegalArgumentException: host must be specified and not empty

Is the sftp host name sftp.myftpserver.com not a valid name?

Further research revealed that the root cause of the issue is the usage of special characters in the password of the ftp user. Let's say the password/username contains the "@" symbol, this causes the connection string created by switchyard to omit the hostname and thus we are getting the error as we shared.

How we can escape the "@" symbols in username/password to make this work.
