Pasquale Congiusti commented on CAMEL-23650:
--------------------------------------------
Hello. That one is on purpose as it is needed by monitoring tools (ie, Camel
Monitor Operator) to scrape metrics when an application is shutting down for
any reason. Indeed the observability services it is the one that include that
and default to WARN. I'm taking over this and add a configuration to control
the logging level, so, we never spam with a warning.
