> The FieldAccessor class in flink-streaming-java has a hard dependency on scala. It would be ideal if we could restrict this dependencies to flink-streaming-scala.
> We could move the SimpleProductFieldAccessor & RecursiveProductFieldAccessor to flink-streaming-scala, and load them in the FieldAccessorFactory via reflection.
> This is one of a few steps that would allow the Java Datastream API to be used without scala being on the classpath.
