Without explicitly adding a null, containsKey() will return false. Is that the expectation? 🤔 I'm not sure why users would need this use case. Storing null in a map seems like a design flaw to me. Additionally, Admin#listOffsets doesn't return null values. -- This is an automated message from the Apache Git Service.
