The Callback interface is a perfect example of a place that can use the functionalinterface in Java. Strictly for Java, this isn't "required" since Java will automatically coerce, but for Clojure (and other JVM languages I belive) to interop with Java lambdas it needs the FunctionalInterface annotation. Since FunctionalInterface doesn't add any overhead and provides compiler-enforced documentation, I don't see any reason *not* to have this. This has already been added into Kafka Streams here: https://github.com/apache/kafka/pull/19234#pullrequestreview-2740742487 I am happy to add it to any other spots in that might be useful too. -- This is an automated message from the Apache Git Service.
