Bug Report

We have two Java services that use dd-trace-java to send traces to Datadog.
Both are configured with the following :
-Ddd.service.mapping=postgresql:$SERVICE_NAME-db,kafka:$SERVICE_NAME-kafka,redis:$SERVICE_NAME-redis

First service use version 2.7.1 of Spring Boot, the "spring.consume" operation is located in the DD service "kafka".
So it is mapped to $SERVICE_NAME-kafka.

Second service is in version 3.2.5 of Spring Boot and the "spring.consume" operation is no more located in DD service "kafka" but the default service name.

On our side, the first behavior ("spring.consume" operation in "kafka") was better as it provide better separation (for P95, traces, etc...) between HTTP requests and Kafka processes.

Is this an intended behavior of the library or it is just a missing mapping for new versions of Spring boot Kafka listener ?
Thanks in advance for your help.
Yours faithfully,
LCDP

Expected Behavior

spring.consume" operation should be located in "kafka" service name.

Reproduction Code

Run an app in Spring-boot 3.2.5 with following code :

JAVA_OPTS="-javaagent:/usr/local/bin/dd-java-agent.jar -Ddd.dbm.propagation.mode=full -Ddd.integration.jdbc-datasource.enabled=true -Ddd.env=$SERVICE_ENVIRONMENT -Ddd.service=$SERVICE_NAME -Ddd.version=$SERVICE_VERSION -Ddd.service.mapping=postgresql:$SERVICE_NAME-db,kafka:$SERVICE_NAME-kafka,redis:$SERVICE_NAME-redis $JAVA_OPTS"

@KafkaListener(
            groupId = "#{__listener.getGroupId()}",
            properties = "#{__listener.getProperties()}",
            topics = "#{__listener.getTopic()}",
            batch = "true")
    public void read(@Payload ConsumerRecords<[...], [...]> records, Acknowledgment ack) {

        doSomething(records);

        ack.acknowledge();
    }
