Github user StephanEwen commented on the issue: https://github.com/apache/flink/pull/2298 Would be great to reflect the "do not use" with proper visibility. A JavaDoc comment is usually not helping at all. Also, the dependency on the java API classes in the Scala classes does not seem right. Usually the Scala classes hide the Java API streams and environments. Both of these things are usually strong indicators that there are some abstraction issues. Would be good to get that right, while the API is fresh and malleable.
