Reporter: Michael Rambichler
If you use a @Produce annotation in an EventNotifier Camel fails at startup.
*Reproducable with:* Custom EventNotifier in a plain Camel + Springboot
Routebuilder.
I have reproduced it with the spring boot example:
[https://github.com/apache/camel-spring-boot-examples/tree/main/spring-boot]
and added the EventNotifier below.
Fails since Camel > 3.11
Initialization of bean failed; nested exception is
org.springframework.beans.factory.BeanCreationException: Error post processing
