> While refactoring the OffsetFetch handling in KafkaApis, we introduced a NullPointerException (NPE). The NPE arises when the FetchOffset API is called with a client using a version older than version 8 and using null for the topics to signal that all topic-partition offsets must be returned. This means that this bug mainly impacts admin tools. The consumer does not use null.
> This NPE is here: https://github.com/apache/kafka/commit/24a86423e9907b751d98fddc7196332feea2b48d#diff-0f2f19fd03e2fc5aa9618c607b432ea72e5aaa53866f07444269f38cb537f3feR237.
> We missed this during the refactor because we had no tests in place to test this mode.
