Is it possible to use `spring-kafka-test` without AssertJ?

Is it possible to use spring-kafka-test without AssertJ?
I've project with kotlin and excluded assertj from spring-boot-starter-test, 'cause we use more kotlin-style assert library and code is really messy when you have two strict library at once. Right now after added dependency spring-kafka-test and enable it, I've java.lang.NoClassDefFoundError: org/assertj/core/util/Arrays. The problem's line of code:

spring-kafka/spring-kafka-test/src/main/java/org/springframework/kafka/test/condition/EmbeddedKafkaCondition.java

Line 110 in cda70d4

.filter(extended -> Arrays.asList(extended.value()).contains(SpringExtension.class))

It's strange to use assertj here, but maybe it's not the one problem.
Is it better to include asstertj to test scope?

Sorry for my English =)

Thanks; it's a bug (wrong import - probably an artifact of the IDE auto-selecting).

I think we need to revise all the classes in spring-kafka-test for an explicit org.assertj imports.
For example KafkaTestUtils really can be used in the same Kotlin-based tests, but really without an AssertJ import.

Also it looks like the current fix won't let us go too far because an EmbeddedKafkaBroker still has that import static org.assertj.core.api.Assertions.assertThat;.

I would even say that all those utils have to be without any assertions. This is really a target test responsibility to check data and state explicitly.
