>                 Key: KAFKA-9490
>                 URL: https://issues.apache.org/jira/browse/KAFKA-9490
>             Project: Kafka
>          Issue Type: Bug
>          Components: streams
>    Affects Versions: 2.4.0
>            Reporter: Dariusz Kordonski
>            Assignee: Matthias J. Sax
>            Priority: Minor
>
> The following methods in {{Grouped}} class seem to be missing generic parameters {{<K,V>}} in the declared return type:
> {code:java}
> public static <K> Grouped keySerde(final Serde<K> keySerde) { return new       Grouped<>(null, keySerde, null); 
> }
> public static <V> Grouped valueSerde(final Serde<V> valueSerde) { return new Grouped<>(null, null, valueSerde); 
> } {code}
> I think it both cases it should be:
> {code:java}
> public static <K,V> Grouped<K,V> ...() {code}
> This causes "unchecked call" compiler warnings when called by clients.
