Error creating bean with name 'embeddedKafka': Invocation of init method failed; nested exception is kafka.common.KafkaException: - spring

Question

I am using the spring cloud contrat to test a kafkaListsener of my service. I use EmbeddedKafka together with the spring cloud contract.
The listener in my service is implemeneted by #KafkaListener from spring kafka.
The contract test I have is like below:
#EmbeddedKafka
#SpringBootTest(classes = {ServiceApplication.class},
properties = {"stubrunner.kafka.enabled=true",
"stubrunner.stream.enabled=false",
"spring.cloud.stream.function.autodetect=false"})
public class EventContractTest {
#Autowired
private StubTrigger stubTrigger;
#SpyBean
#Qualifier("KafkaEventListener")
private EventListener eventListener;
#BeforeEach
public void setup() throws ExecutionException, InterruptedException {
Mockito.doNothing().when(eventListener).onEventReceived(any(), any());
}
#Test
public void kafkaEventTest() throws ExecutionException, InterruptedException {
stubTrigger.trigger("kafka-event");
ArgumentCaptor<Event> eventArgumentCaptor = ArgumentCaptor.forClass(Event.class);
ArgumentCaptor<Bytes> headerArgumentCaptor = ArgumentCaptor.forClass(Bytes.class);
verify(eventListener, timeout(5000).times(1)).
onEventReceived(eventArgumentCaptor.capture(), headerArgumentCaptor.capture());
....
}
#Test
public void kafkaEventTest2() throws ExecutionException, InterruptedException {
stubTrigger.trigger("kafka-event-2");
ArgumentCaptor<Event> eventArgumentCaptor = ArgumentCaptor.forClass(Event.class);
ArgumentCaptor<Bytes> headerArgumentCaptor = ArgumentCaptor.forClass(Bytes.class);
verify(eventListener, timeout(5000).times(1)).
onEventReceived(eventArgumentCaptor.capture(), headerArgumentCaptor.capture());
....
}
}
when run the tests case, in most cases it will pass, but it will randomlly fail with the following exception:
givenEventFromContract_whenCancelSubscription_thenTriggerSubscriptionChangedKafkaEvent
Time elapsed: 0.002 s <<< ERROR! 14:12:43
java.lang.IllegalStateException: Failed to load ApplicationContext
14:12:43 Caused by:

Time elapsed: 25.891 s <<< ERROR! 14:12:43

And below are my kafka relevant configuration:
# -- Kafka with PLAINTEXT authentication --
com.sap.kafka.enabled=false
spring.kafka.bootstrap-servers=${spring.embedded.kafka.brokers}
spring.kafka.consumer.group-id=test
spring.kafka.consumer.properties.auto.offset.reset=earliest
spring.kafka.topics.default.replication-factor=1
spring.kafka.topics.default.partition-count=1
spring.kafka.topics.default.min-in-sync-replicas=1
Does someone know what was the issue? is this a bug of spring kafka?
