> User feedback: When type extraction fails in the {{AbstractDeserializationSchema}}, the error message does not explain fully how to fix this.
> I suggest to improve the error message and add some convenience constructors to directly pass TypeInformation when needed.
> We can also simplify the class a bit, because TypeInformation needs no longer be dropped during serialization.
