-------------------------------------
Summary: Integer Overflow Possible with CircularIterator
Key: KAFKA-9419
URL: https://issues.apache.org/jira/browse/KAFKA-9419
Project: Kafka
Issue Type: Improvement
Reporter: David Mollitor
Very unlikely to happen, but as someone that gets called in when something goes
wrong, I'd like to remove as many possibilities as possible.
[https://github.com/apache/kafka/blob/8c21fa837df6908d9147805e097407d006d95fd4/clients/src/main/java/org/apache/kafka/common/utils/CircularIterator.java#L39-L43]
Also, the current implementation will work with a LinkedList, but it won't work
well. The constant call to `get(i)` will perform at O(n^2). Using an iterator
instead allows other Collections to work reasonably well.
