Mykola Polonskyi commented on AVRO-1927:
----------------------------------------
hello (bump message)
*same behavior from builder on 1.8.2 and same error onto serialization call*
can any one share reference for spec that explain this behavior if its valid?
or clarify status
tnx
> If a default value is set, Avro allows null values in non-nullable fields.

> Key: AVRO-1927
> URL: https://issues.apache.org/jira/browse/AVRO-1927
> Project: Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.8.1
> Reporter: Andreas Maier
> Priority: Major
>
> With an avro schema like
> {code}
> {
> "name": "myfield",
> "type": "string",
> "default": ""
> }
> {code}
> the following code should throw an exception
> {code}
> MyObject myObject = MyObject.newBuilder().setMyfield(null).build();
> {code}
> But instead the value of myfield is set to null, which causes an exception
> later when serializing myObject, because null is not a valid value for
> myfield.
> I believe in this case setMyfield(null) should throw an exception,
> independent of the value of default.
