Apache Camel FTP Download not deleting remote file

First of all: I'm pretty new to Apache Camel and Stack Overflow!

I created a route that filters and downloads files from an SFTP server and removes them after processing.

My problem: On my local machine, the route works fine. When I deploy this route (same .war) to the production server, the download is done, but when the FTP component tries to delete the file, I get the below exception. The dev and production machine has one camel version, tomcat and java. The only difference is the OS (Dev: Windows 7, Prod: Windows Server 2008 R2)

Any ideas ???

Here's the route:

        String uri = "sftp://" + sftpUserId + "@" + sftpHost + "?" +
                "password=" + sftpPassword + "&" +
                "recursive=true" + "&" +                
                "filter=#fileFilter" + "&" +  
                "binary=true" + "&" +
                "delete=true";
