Hi, We have seen something similar in Flink 1.2. We have an operation that parses some JSON, and when it fails to parse it, we can see the ClassNotFoundException for the relevant exception (in our case JsResultException from the play-json library). The library is indeed in the shaded JAR, otherwise we would not be able to parse the JSON.
