dajac opened a new pull request #8990: URL: https://github.com/apache/kafka/pull/8990
This PR fixes a bug introduced in https://github.com/apache/kafka/pull/8683/. While processing connection set up timeouts, we are iterating through the connecting nodes to process timeouts and we disconnect within the loop, removing the entry from the set in the loop that it iterating over the set. That raises an `ConcurrentModificationException` exception. The current unit test did not catch this because it was using only one node. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
