> https://issues.apache.org/jira/browse/AVRO-2514 improved serialization error
> messages greatly by providing more information about the "location" of a
> piece of erroneous data in the object graph handed to a serializer.
>
> however, a few more things can be improved:
> * no info printed about which union branches were selected/used
> * no info printed about array indexes or map keys
> * (subjective) text could be made more concise.
