> The implementation of KAFKA-5291 introduced a check for old Brokers compatibility falling back to _*true*_ in *MetadataRequest allowAutoTopicCreation* field for some operations like *describeTopics*.
> Then, after that backward-compatibility changes, more methods were added to *AdminClient* like *listOffsets* [KIP-396|https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=97551484] which unfortunately don't have compatibility with old Brokers into account. One might argue that, given that new methods were not present previously, it's not a compatibility break. While this is strictly true, I believe that one of Kafka Clients' most appreciated feature is the ability to use old Brokers with new Clients.
> I've prepared a small PR to fix for this, following the same approach used in KAFKA-5291.
