Simon Cooper created KAFKA-3837: ----------------------------------- Summary: Report the name of the blocking thread when throwing ConcurrentModificationException Key: KAFKA-3837 URL: https://issues.apache.org/jira/browse/KAFKA-3837 Project: Kafka Issue Type: Improvement Components: clients Affects Versions: 0.9.0.1 Reporter: Simon Cooper Priority: Minor
{{KafkaConsumer.acquire}} throws {{ConcurrentModificationException}} if the current thread it does not match the {{currentThread}} field. It would be useful if the name of the other thread was included in the exception message to help debug the problem when this exception occurs. As it stands, it can be really difficult to work out what's going wrong when there's several threads all accessing the consumer at the same time, and your existing exclusive access logic doesn't seem to be working as it should. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
