> Key: KAFKA-19206
> URL: https://issues.apache.org/jira/browse/KAFKA-19206
> Project: Kafka
> Issue Type: Bug
> Components: clients, consumer
> Affects Versions: 4.0.0
> Reporter: Kirk True
> Assignee: Kirk True
> Priority: Major
> Labels: kip-848-client-support
> Fix For: 4.1.0
>
>
> The {{ConsumerNetworkThread}} initializes its {{NetworkClientDelegate}} and
> {{RequestManagers}} objects in {{{}initializeResources(){}}}. If either
> object fails its initialization, an error is thrown, causing the
> {{AsyncKafkaConsumer}} to close. During the consumer close process, the
> {{ConsumerNetworkThread}} calls its {{cleanup()}} method, but a
> {{NullPointerException}} will be thrown when attempts to dereference either
> the {{NetworkClientDelegate}} and/or {{RequestManagers}} objects.
