in micronaut-platform-4.6.x.pom they are importing the same dependency org.apache.kafka:kafka-clients with different version !!! :

<dependency>
        <groupId>org.apache.kafka</groupId>
        <artifactId>kafka-clients</artifactId>
        <version>${kafka.compat.version}</version>
</dependency>
<dependency>
        <groupId>org.apache.kafka</groupId>
        <artifactId>kafka-clients</artifactId>
        <version>${kafka.version}</version>
</dependency>

with

<kafka.compat.version>3.8.0</kafka.compat.version>
<kafka.version>3.7.0</kafka.version>
