Description

Seen recently: https://jenkins.confluent.io/job/kafka-trunk/1143/testReport/org.apache.kafka.clients.consumer.internals/ConsumerCoordinatorTest/testAutoCommitDynamicAssignment/.

java.lang.NullPointerException
	at org.apache.kafka.clients.consumer.internals.ConsumerCoordinatorTest.testAutoCommitDynamicAssignment(ConsumerCoordinatorTest.java:821)

Looks like it's caused by a race condition with the heartbeat thread.
