> There seems to be an issue with [stringable
> fields|https://issues.apache.org/jira/browse/AVRO-1146] that are nullable.
> I'm mostly using ReflectData.AllowNull in my real usage of this feature and
> I'm seeing it fail with this:
> {code}
> org.apache.avro.AvroRuntimeException: Unknown datum type: 10
> at
> org.apache.avro.generic.GenericData.getSchemaName(GenericData.java:574)
> at
> org.apache.avro.generic.GenericData.resolveUnion(GenericData.java:539)
> at
> org.apache.avro.generic.GenericDatumWriter.resolveUnion(GenericDatumWriter.java:137)
> at
> org.apache.avro.generic.GenericDatumWriter.write(GenericDatumWriter.java:70)

> org.apache.avro.reflect.ReflectDatumWriter.write(ReflectDatumWriter.java:104)
> at
> org.apache.avro.generic.GenericDatumWriter.write(GenericDatumWriter.java:57)
> {code}
> Here's a quick test that shows this problem:
> {code}
> public static class N1 {
> BigDecimal number;
> }
> @Test public void testNullableStringableField() throws Exception {
> N1 datum = new N1();
> datum.number = BigDecimal.TEN;
> checkBinary(ReflectData.AllowNull.get(),
> ReflectData.AllowNull.get().getSchema(N1.class), datum, false);
> }
> {code}
