Inconsistent kamelet behaviour between DSLs

[eshepelyuk]

What happened?

While creating integration in JAVA DSL that leverages custom defined kamelets, I am receiving errors.
Meanwhile the same integration works when defined in YAML DSL.

Steps to reproduce

1. Create sample kamelets

---
apiVersion: camel.apache.org/v1
kind: Kamelet
metadata:
  name: mytimer
  namespace: default
spec:
  template:
    from:
      uri: "timer:tick?includeMetadata=true&period=5000"
      steps:
        - to: "kamelet:sink"
---
apiVersion: camel.apache.org/v1
kind: Kamelet
metadata:
  name: mylog
  namespace: default
spec:
  template:
    from:
      uri: "kamelet:source"
      steps:
        - log: "${headers}"

2. Create JAVA DSL integration, using both kamelets

import org.apache.camel.builder.RouteBuilder;

public class MyJava extends RouteBuilder {
    @Override
    public void configure() throws Exception {
        from("kamelet:mytimer")
            .to("kamelet:mylog");
    }
}

3. Run integration with
   kamel run MyJava.java --dev
