> Camel FTP component fails to process multiple files at once from a specified folder (let's
assume the folder is /in).
> When the consumer connects to a ftp account and finds a list of, let's say, 3 files,
it will try to retrieve them in parallel but this is not handled properly.
> As you can see from the below FTP server log, this is what Camel FTP does:
> - it changes the current directory to /in
> - retrieves the file
> - it changes the current directory to /
> - the second (probably) thread changes the directory to /in
> - retreives the second file
> - the first (probably) thread sends a delete command but it sends it as if it were in
the root folder but it is actually in the /in folder
> - the FTP gives an error that the file doesn't exist
> - somehow the FTP Component blocks itself on the first file...
