dennis lucero commented on AVRO-1400:
-------------------------------------

An alternative fix instead of the suggested annotation would be to allow "default" \
for @AvroMeta with a change in org.apache.avro.Schema:344.

> Key: AVRO-1400
> URL: https://issues.apache.org/jira/browse/AVRO-1400
> Project: Avro
> Issue Type: Improvement
> Components: java
> Affects Versions: 1.7.5
> Reporter: dennis lucero
> Labels: annotation, features, reflection, schema
> 
> It would be nice if there was an annotation in org.apache.avro.reflect to specify \
> default values for schemata derived reflectively, allowing for proper schema \
> evolution. I suggest the following:
> {code:java}
> @AvroDefault(1)
> int someNum;
> @Nullable
> @AvroDefault(null)
> AnotherRecord myRec;
> {code}
