John Roesler commented on KAFKA-8315:
-------------------------------------

Hey [~the4thamigo_uk], 

Sorry about that. It looks like the javadoc got messed up in this change: https://github.com/apache/kafka/pull/5911/files#diff-35e3523474fa277a63e36a3fe9e22af8

I'll submit a PR to fix it.

In summary, you should use the JoinWindows "grace period" instead of "until".

> 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.
