[jira] [Commented] (AVRO-2522) Specific API doesn't handle schemas with IList or Nullable in name

    [ https://issues.apache.org/jira/browse/AVRO-2522?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16920535#comment-16920535 ] 

Sean Busbey commented on AVRO-2522:
-----------------------------------

How close is this to landing? it's not marked as a blocker; would it be fine waiting for 1.9.2?

> The Specific API in the C# bindings do not properly handle:
>  * Schemas with {{IList}} in their name
>  * Schemas with {{Nullable}} in their name
>  * Arrays of nullables (see example schema below)
> These throw an exception from the {{ObjectCreator}} indicating that it could not find the type.
> This sample application on GitHub demonstrates these problems: [https://github.com/blachniet/AVRO-2522].
> Here's a sample schema containing an array of nullables that triggers this problem.
> {code:java}
> {
>   "namespace": "AvroListOfLists.Records",
>   "name": "MyRecord",
>   "type": "record",
>   "fields": [
>     {
>       "name": "MyList",
>       "type": {
>         "type": "array",
>         "items": ["null", "int"]
>       }
>     }
>   ]
> }
> {code}
