Description

I have a known_hosts file in \src\main\resources and I want the ftp-component to use this known_hosts file when connecting to an sftp server (and not be dependent on the ~/.ssh/known_hosts file).
When using this option (in combination with the option useUserKnownHostsFile=false), camel starts up fine

if (isNotEmpty(sftpConfig.getKnownHostsFile())) {

is being triggered from SftpOperations.java and I can see that useUserKnownHostsFile and knownHostsFile is set correctly - seen in this picture:

However when some files are added to SFTP server and

if (isNotEmpty(sftpConfig.getKnownHostsFile())) {

triggers then the values are overridden:

In logs I see these repeating lines each time a file is added to SFTP server:

..
