    Some small comments, otherwise +1 to merge.
    Integration into the TypeExctractor can be a separate issue, in my opinion.

>             Project: Flink
>          Issue Type: New Feature
>          Components: Java API
>    Affects Versions: 0.10.0

>             Fix For: 1.0.0
> Either types are recurring patterns and should be serialized efficiently, so it makes
sense to add them to the core Java API.
> Since Java does not have such a type as of Java 8, we would need to add our own version.
> The Scala API handles the Scala Either Type already efficiently. I would not use the
Scala Either Type in the Java API, since we are trying to get the {{flink-java}} project "Scala
free" for people that don't use Scala and o not want to worry about Scala version matches
and mismatches.
