Hi [~jlaskowski], Are you working on this? Should I pick if not?

>                 Key: KAFKA-7446
>                 URL: https://issues.apache.org/jira/browse/KAFKA-7446
>             Project: Kafka
>          Issue Type: Improvement
>          Components: streams
>    Affects Versions: 2.0.0
>            Reporter: Jacek Laskowski
>            Priority: Trivial
>              Labels: newbie++
>
> The following code throws a {{IllegalArgumentException}}.
> {code:java}
> import org.apache.kafka.streams.kstream.TimeWindows
> import scala.concurrent.duration._
> val timeWindow = TimeWindows
> .of(1.minute.toMillis)
> .advanceBy(2.minutes.toMillis)
> {code}
> The exception is as follows and it's not clear why {{60000}} is the upper limit (not to mention that {{AdvanceMs}} with the uppercase {{A}} did also confuse me).
> {code:java}
> java.lang.IllegalArgumentException: AdvanceMs must lie within interval (0, 60000].
> at org.apache.kafka.streams.kstream.TimeWindows.advanceBy(TimeWindows.java:100)
> ... 44 elided{code}
> I think that the message should be more developer-friendly and explain the boundaries, perhaps with an example (and a link to docs)?
