Camel Kafka Kafka Connector Problem Showcase

Simple project showcasing the Camel Kafka Kafka Connector issue. The problem is, that the connector is not passing forward the message key that comes from the inbound topic.

[EDIT] After changes introduced by Andrea (thank U very much) it's working and tests are passing!

Intro

This project contains simple Spring Boot app with ShowcaseTest, which is currently failing expecting the connector not to lose the message key in between working. You can also see exactly the same behavior using prepared docker-compose file, and while running the DemoApplication, in the logs you will see that on the outbound topic the key is missing there.

How to set it up?

1. Run setup.sh - downloads the connector and places it in connectors folder.
2. Run docker-compose up -d - to make the whole infra work.
3. Run register-camel-connector.sh - registers the Camel Kafka Kafka Connector.
4. Build app using mvn clean package -DskipTests.
5. Run the app using mvn spring-boot:run.
6. Run sample-request.sh to see the issue working solution in the console.

OR

Build the project with mvn clean package and see that the ShowcaseTest is failing due to missing key in outbound topic passing.
