> 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: 
> {noformat}
> 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
>         at org.apache.kafka.tools.VerifiableProducer.send(VerifiableProducer.java:232)
>         at org.apache.kafka.tools.VerifiableProducer.run(VerifiableProducer.java:462)
>         at org.apache.kafka.tools.VerifiableProducer.main(VerifiableProducer.java:500)

> 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.
