I'm using camel-jaxb-starter 2.23.0 in combination with Spring Boot 2.1.1.
During start-up this warning is displayed:
WARN 15204 — [ main] o.a.c.i.DefaultCamelBeanPostProcessor : No CamelContext defined yet so cannot inject into bean: org.apache.camel.converter.jaxb.FallbackTypeConverter
Otherwise everything is working fine (as far as I can tell).
I created a minimal project that allows reproducing this warning: https://github.com/PascalSchumacher/CamelJaxbStartupWarning
