Many thanks Tom, that works as expected. Just out of interest, when would you 
use GenericData.Record over the GenericRecordBuilder?

[jira] [Created] (AVRO-1949) Not setting a non-null field in GenericRecord causes a NullPointer exception on Serialisation even though a default is defined in the schema

[Mike Hurd (JIRA)]

 Summary: Not setting a non-null field in GenericRecord causes a 
NullPointer exception on Serialisation even though a default is defined in the 
schema
 Key: AVRO-1949
 URL: https://issues.apache.org/jira/browse/AVRO-1949
 Project: Avro
  Issue Type: Bug
  Components: java
Affects Versions: 1.8.1
 Environment: Windows 7, JDK8
Reporter: Mike Hurd
Priority: Minor


As per the summary, I had a search through the existing JIRAs but couldn't find 
a match apologies if this is a duplicate:

example schema:

{noformat}
{"namespace": "example.data",
  "type": "record",
  "name": "Data",
  "fields": [
{"name": "name", "type": "string"},
{"name": "favorite_season", "type": "string", "default": "Autumn"}
  ]
}
{noformat}
{noformat}
GenericRecord record = new GenericData.Record(schema);
record.put("name", "my name");
{noformat}
Serialising the above throws a NullPointerException:
{noformat}
java.lang.NullPointerException: null of string in field favorite_season of 
example.data.Data
at 
org.apache.avro.generic.GenericDatumWriter.npe(GenericDatumWriter.java:145) 
~[classes/:?]
at 
org.apache.avro.generic.GenericDatumWriter.writeWithoutConversion(GenericDatumWriter.java:139)
 ~[classes/:?]
at 
org.apache.avro.generic.GenericDatumWriter.write(GenericDatumWriter.java:75) 
~[classes/:?]
at 
org.apache.avro.generic.GenericDatumWriter.write(GenericDatumWriter.java:62) 
~[classes/:?]
{noformat}

Surely, given that the schema is available the writeField method should check 
to see if there is a default field available to use if the required field does 
not have a value supplied (and is not-null).
