Hi Peter, When CAMEL-8202 has been fixed, the isUseUserKnownHostsFile might have been added to preserve the default behaviour across the camel 2.x line. But then, the default value should have been false and you would not have been impacted.
At the end of the day, setting this option to false is needed as a workaround in camel 2.x. However, I wonder if your idea could deserve creating a ticket against camel-3.x. Cheers, Alex <https://issues.apache.org/jira/browse/CAMEL-8202>
