Raymond commented on CAMEL-17391:
---------------------------------
[~ncasaux] / [~davsclaus] I tested the suggested solution and can confirm it
works.
Note that I don't have any special code for Elastic in my application (The word
elastic or sniffer are not part of code). Also, when I check the dependency
tree with Gradle, there aren't any Elastic related libraries. It's only when
the Camel elastic dependency (which includes
org.elasticsearch.client:elasticsearch-rest-client-sniffer) that the
autoconfiguration of Spring Boot interferes. This seems not to happen with
older versions somehow (I had Spring Boot 2.2 with Camel 3.7.x before).
