-------------------------------------

             Summary: ReflectData.AllowNull incorrectly handles primitive types.
                 Key: AVRO-1588
                 URL: https://issues.apache.org/jira/browse/AVRO-1588
             Project: Avro
          Issue Type: Bug
    Affects Versions: 1.7.7
            Reporter: Joey Echeverria


When doing the following:
{code:java}
private static class PoJo {
  private long id;
  private String name;
}

ReflectData.AllowNull.get().getSchema(PoJo.class);
{code}

I'd expect a schema like this:
{code:javascript}
{
  "type" : "record",
  "name" : "PoJo",
  "namespace" : "MyObject$",
  "fields" : [ {
    "name" : "id",
    "type" : "long",
  }, {
    "name" : "name",
    "type" : [ "null", "string" ],
    "default" : null
  } ]
}
{code}

But instead I get:
{code:javascript}
{
  "type" : "record",
  "name" : "PoJo",
  "namespace" : "MyObject$",
  "fields" : [ {
    "name" : "id",
    "type" : [ "null", "long" ],
    "default" : null
  }, {
    "name" : "name",
    "type" : [ "null", "string" ],
    "default" : null
  } ]
}
{code}

This will later result in an NullPointerException when you try to deserialize 
bytes where id was null when it tries to convert the Long to a long.
