-------------------------------------

the issue #AVRO-2514 improves the message but is still not very useful in cases where we have several domains

>             Project: Apache Avro
>          Issue Type: Improvement
>          Components: java
>    Affects Versions: 1.8.2, 1.10.0, 1.9.2

> In current versions, when a field cannot be written, an exception is thrown but it is not possible to know which field generated an error.
> Ex:
>  
> {code:java}
> record Bacon {
>   long id;
>   string description;
> }
> {code}
>  
> When a bacon with a null and serialized description only one NPE is launched without specifying which field was in error, the same occurs if the value cannot be serialized due to type incompatibility
