Yeah, if you weren't already running it, try upgrading Streams to 2.6. They recently added support for "all" platforms to rocksdb and we updated the dependency to get this fix in 2.6. See KAFKA-9225 <https://issues.apache.org/jira/browse/KAFKA-9225>
If you already were running 2.6, then, that's unfortunate.
