> Hi there.
> According to http://camel.apache.org/asynchronous-routing-engine.html 
> camel-ftp can be run async.
> However it is not possible since 
> {{org.apache.camel.component.file.remote.RemoteFileConsumer#processExchange}} 
> sets an exchange property {{Exchange.UNIT_OF_WORK_PROCESS_SYNC}} to {{true}} 
> and in {{org.apache.camel.processor.CamelInternalProcessor#process}} this 
> property gets evaluated and the processor is not running in async.
> The comment in {{processExchange}} states that "mark the exchange to be 
> processed synchronously as the ftp client is not thread safe" - the ftp 
> client or the library? If the library is meant, is jsch for sftp, thread 
> safe? Shouldn't this code be in the {{FTPConsumer}} class?
> Also {{FromFtpAsyncProcessTest}} is kinda wired because it uses its own 
> executor service to run async?
> When async processing from an ftp espically sftp source is not possible the 
> following code does not work as expected either
> {code}
>         onException(Exception.class)
>                 .maximumRedeliveries(maxTries)
>                 .redeliveryDelay(TimeUnit.HOURS.toMillis(delay))
>                 .continued(true);
> {code}
