> Project: Apache Avro
> Issue Type: Task
> Components: java

> Fix For: 1.9.0
>
>
> After making {{Schema.Field#defaultValue}} package private, there is no way
> to distinguish whether a Field has a default value of 'null' or has no
> default at all. This is a breaking change, notably affecting Hortonworks
> Schema Registry. See discussion here:
> [https://github.com/hortonworks/registry/pull/547]
> I propose we should make that method public and still deprecated. Otherwise I
> don't see a clear way to release a version of the Hortonworks registry that
> will be compatible with both Avro 1.8.x and 1.9.0.
