             Summary: NoSuchMethodError when creating ProducerRecord in upgrade system tests
                 Key: KAFKA-6053
                 URL: https://issues.apache.org/jira/browse/KAFKA-6053
             Project: Kafka
          Issue Type: Bug
            Reporter: Apurva Mehta
            Assignee: Apurva Mehta


This patch https://github.com/apache/kafka/pull/4029 used a new constructor for {{ProducerRecord}} which doesn't exist in older clients. Hence system tests which use older clients fail with:

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.kafka.clients.producer.ProducerRecord.<init>(Ljava/lang/String;Ljava/lang/Integer;Ljava/lang/Long;Ljava/lang/Object;Ljava/lang/Object;)V

A trivial fix is to only use the new constructor if a message create time is explicitly passed to the VerifiableProducer, since older versions of the test would never use it.
