> The documentation says to use `Materialized` not `JoinWindows.until()` ([https://kafka.apache.org/22/javadoc/org/apache/kafka/streams/kstream/JoinWindows.html#until-long-]), but there is no where to pass a `Materialized` instance to the join operation, only to the group operation is supported it seems.

> [Additional]
> From what I understand, the retention period should be independent of the grace period, so I think this is more than a documentation fix (see comments below)
