Andreas Maier created AVRO-1927:
-----------------------------------
Summary: If a default value is set, Avro allows null values in
non-nullable fields.
Key: AVRO-1927
URL: https://issues.apache.org/jira/browse/AVRO-1927
Project: Avro
Issue Type: Bug
Components: java
Affects Versions: 1.8.1
Reporter: Andreas Maier
With an avro schema like
{code}
{
"name": "myfield",
"type": "string",
"default": ""
}
{code}
the following code should throw an exception
{code}
MyObject myObject = MyObject.newBuilder().setMyfield(null).build();
{code}
But instead the value of myfield is set to null, which causes an exception
later when serializing myObject, because null is not a valid value for myfield.
I believe in this case setMyfield(null) should throw an exception, independent
of the value of default.
