   @nandorKollar - I ran into this issue today, and I'm interest in carrying 
this into master.  Any issues using your work as a starting point and adding 
you as signed off by on the commits?  I can run them by you first if you'd 
like.  Thanks

>            Assignee: Nandor Kollar

>         Attachments: unitTestDefaultNull.patch
> I was creating GenericRecords and populating some fields -- which i could not 
> find the content on some json files -- with the Schema.Field.defaultVal(). 
> It seems if the schema has explicitly set the default value to be null, the 
> records generated this way can't be written. In this case, if default value 
> is null in the schema, an instance of 
> org.apache.avro.JsonProperties.NULL_VALUE is returned by 
> Schema.Field.defaultVal().
> I created an unit test which replicates the bug. I was thinking modify the 
> class org.apache.avro.generic.GenericData to evaluate 
> org.apache.avro.JsonProperties.NULL_VALUE as null. Is this the way to go? or 
> org.apache.avro.JsonProperties.NULL_VALUE is intend for other purposes?
