    • Fuse 7.3 Sprint 39

      I try to configure REST endpoint using REST DSL with API doc (swagger). I want to use HTTPS protocol. (See attached reproducer)

      I am getting following error on spring-boot:

      Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

      The problem is on line https://github.com/apache/camel/blob/master/components/camel-undertow/src/main/java/org/apache/camel/component/undertow/UndertowComponent.java#L334. Spring-boot application creates new UndertowHost even if suitable host is present.

      When I bypass this behavior both endpoints (swagger and the REST one) are working.
