Kirk True updated KAFKA-19206:
------------------------------
Description: 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. (was: 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.)
> ConsumerNetworkThread.cleanup() throws NullPointerException if
> initializeResources() failed
