> Upgraded to Avro 1.9.2 and found when using the withDefault method in
> SchemaBuilder.GenericDefault to set default value for a Double typed field,
> it cannot set Double.NaN correctly, throwing out below error:
> {code}
> Exception in thread "main" org.apache.avro.AvroTypeException: Invalid
> default for field field: "NaN" not a "double"
> at org.apache.avro.Schema.validateDefault(Schema.java:1540)
> at org.apache.avro.Schema.access$500(Schema.java:87)
> at org.apache.avro.Schema$Field.<init>(Schema.java:521)

> org.apache.avro.SchemaBuilder$FieldBuilder.completeField(SchemaBuilder.java:2238)

> at
> org.apache.avro.SchemaBuilder$GenericDefault.withDefault(SchemaBuilder.java:2545)
> {code}
> After debugging it seemed the *toJsonNode* method in SchemaBuilder is
> returning a TextNode rather than a NUMBER typed one.
> The problem can be replicated using below sample code:
> {code}
> SchemaBuilder.FieldBuilder fieldBuilder =
> SchemaBuilder.record("record").fields().name("field");
> Schema fieldSchema = Schema.create(Schema.Type.DOUBLE);
> SchemaBuilder.GenericDefault genericDefault = fieldBuilder.type(fieldSchema);
> genericDefault.withDefault(Double.NaN);
> // Exception thrown
> {code}
