Tests fail to start using spring-kafka-test (NoClassDefFoundError) - spring

Question

I am testing a feature that uses a Kafka producer and listener, with the help of spring-kafka-test.
Both spring-kafka and spring-kafka-test are using the 2.8.2 version.
My test classes use the #EmbeddedKafka annotation as follows:
#SpringBootTest
#DirtiesContext
#EmbeddedKafka(partitions = 1, brokerProperties = { "listeners=PLAINTEXT://localhost:9092", "port=9092" })
class EmbeddedKafkaIntegrationTest {
// Test cases
}
I get the following stacktrace as I run the tests:
Failed to resolve parameter [com.my-company.my-app.kafka.KafkaProducer kafkaProducer] in constructor [public com.my-company.my-app.kafka.DigitalKafkaListenerIT(com.my-company.my-app.kafka.KafkaProducer,com.my-company.my-app.config.ApplicationProperties)]: Failed to load ApplicationContext

This is possibly a bug in the 2.8.2 version of spring-kafka-test.
Switching back to latest minor 2.7.10 version solved the issue, even though spring-kafka is still on 2.8.2.
