discussuion happened in the code review of the pull request for more
information.
> Report the name of the blocking thread when throwing

> 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
> Assignee: Bharat Viswanadham
> 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.
