> 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 creates a new NetworkClient, which connects to and
> authenticates against a broker. If the authentication fails, the
> NetworkClient throws an error, causing the AsyncKafkaConsumer to close.
> During the consumer close process the ConsumerNetworkThread is closed, but it
> throws a NullPointerException when it attempts to use the requestManagers
> and/or networkClientDelegate objects.
