[jira] [Created] (KAFKA-19651) Thread is not marked interrupted even when AsyncKafkaConsumer.close() throws InterruptException

Kirk True created KAFKA-19651:
---------------------------------

             Summary: Thread is not marked interrupted even when AsyncKafkaConsumer.close() throws InterruptException
                 Key: KAFKA-19651
                 URL: https://issues.apache.org/jira/browse/KAFKA-19651
             Project: Kafka
          Issue Type: Bug
          Components: clients, consumer
    Affects Versions: 4.1.0
            Reporter: Kirk True
            Assignee: Kirk True


There is a unit tests which perform these steps:
 # Create consumer
 # Interrupt thread
 # Call Consumer.close()
 # Check that InterruptException was thrown
 # Call Thread.interrupted()

In those cases, the return value from Thread.interrupted() is actually false. We're catching the interrupted in the close() method but not restoring it before we throw. This is inconsistent with the ClassicKafkaConsumer.
