> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.7.6
> Reporter: Sachin Goyal
> Priority: Major
>
> UnresolvedUnionException is thrown if the following structure is serialized with ReflectData.AllowNull
> (Plain ReflectData works fine)

> class Base
> {
> Integer a = 5;
> }
> class Derived extends Base
> {
> String b = "Foo";
> }
> class PolymorphicDO
> {
> Base obj = new Derived();
> }
> // Serialization code:
> ReflectData rdata = ReflectData.AllowNull.get();
> Schema schema = rdata.getSchema(PolymorphicDO.class);
> ReflectDatumWriter<T> datumWriter = new ReflectDatumWriter (PolymorphicDO.class, rdata);
> DataFileWriter<T> fileWriter = new DataFileWriter<T> (datumWriter);
> fileWriter.create(schema, new ByteArrayOutputStream());
> fileWriter.append(new PolymorphicDO());
> {code}
