> I was running the PlaintextConsumer to test the async consumer; however, a few tests were failing with not being able to verify the listener is invoked correctly
> For example `testPerPartitionLeadMetricsCleanUpWithSubscribe`
> Around 50% of the time, the listener's callsToAssigned was never incremented correctly.  Event changing it to awaitUntilTrue it was still the same case
> {code:java}
> consumer.subscribe(List(topic, topic2).asJava, listener)
> val records = awaitNonEmptyRecords(consumer, tp)
> assertEquals(1, listener.callsToAssigned, "should be assigned once") {code}
