Unlimited maximumReconnectAttempts for camel ftp component

Issue

• When sending files to ftp, there is a parameter maximumReconnectAttempts which "Specifies the maximum reconnect attempts Camel performs when it tries to connect to the remote FTP server".
• It was expected the number of reconnect attempts to be unlimited if maximumReconnectAttempts=0.
• However, having maximumReconnectAttempts=0 actually sets number of attempts to zero, i.e. as soon as connection attempt fails, Camel never retries.
• Is it how it is supposed to be or is it a bug?
