Doug Cutting commented on AVRO-387:
-----------------------------------
Scott> But I have a suspicion that we'll have a need to add to the
SpecificRecord interface at some point.
I do too, so my instinct is to leave it as a marker for now.
Scott> Maybe SpecificRecordBase should just be renamed SpecificRecord and
changed to implement IndexedRecord?
Currently SpecificData uses the SpecificRecord interface, which folks could
implement differently, not with SpecificRecordBase. I'm not convinced we
should discard that yet.

> Key: AVRO-387
> URL: https://issues.apache.org/jira/browse/AVRO-387
> Project: Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.2.0
> Reporter: Michael Armbrust
> Priority: Minor

> This is a very similar issue to AVRO-382, except this time it happens for
> uninitialized unions instead of primitive fields. Once again, this makes it
> very difficult to use avro from the scala console.
> Stacktrace:
> {noformat}
