Hi, I've created pull request. jira: [19328](https://issues.apache.org/jira/browse/KAFKA-19328) problem: 1. doAnswer chaining works as intended only when calls are made sequentially. In a multithreaded environment, its behavior is unpredictable. 2. errors in a thread can be swallowed, not seen in main thread. 3. 5 doAnswer chain is not enough for 100 threads. The last chain is returned for most cases. 4. I am not sure if this is true, but nextFetchOffset seems to be called out of doAnswer chain, so the last values (25, 5, 26, 16) was found in doAsnwer chain. solution: Delete doAnswer chain so that above three problems automatically disappear. -- This is an automated message from the Apache Git Service.
