## Context This test failed in several PR, and from one of the failed build, there was an error log ``` [2024-03-12 13:58:12,744] ERROR Failed to discover HeaderConverter in classpath: Unable to instantiate TestConverterWithPrivateConstructor: Plugin class default constructor must be public (org.apache.kafka.connect.runtime.isolation.ReflectionScanner:138) java.lang.IllegalAccessException: class org.apache.kafka.connect.runtime.isolation.ReflectionScanner cannot access a member of class org.apache.kafka.connect.integration.ConnectorValidationIntegrationTest$TestConverterWithPrivateConstructor with modifiers "private" ``` in [this build](https://ci-builds.apache.org/job/Kafka/job/kafka-pr/job/PR-15463/4/testReport/junit/org.apache.kafka.connect.mirror.integration/IdentityReplicationIntegrationTest/Build___JDK_11_and_Scala_2_13___testReplicateFromLatest__/).
