[jira] [Assigned] (AVRO-2771) Java 1.9.X doesn't allow having Error in a Record

> -------------------------------------------------
>
> Key: AVRO-2771
> URL: https://issues.apache.org/jira/browse/AVRO-2771
> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.9.0, 1.9.1, 1.9.2
> Reporter: Chris Dessonville
> Assignee: Oscar Westra van Holthe - Kind
> Priority: Major
>
> While trying to upgrade from AVRO 1.8.2 to 1.9.X, we hit an unexpected compilation error. The same code works fine in 1.8.2 and even sends over the wire correctly, so it's definitely been supported historically. The issue occurs when you put an {{error}} inside of a {{record}}. I've created a project (further below) to show the issue.

> The errors seen is this:

> Commands you can use (defaults to 1.8.2 since that compiles):
> {code:java}
> mvn install -Davro.version=1.9.2
> mvn install -Davro.version=1.8.2{code}
>
> In terms of solutions, I'd love to see the old behavior restored. However, if avro is moving to stop supporting an {{error}} in a {{record}}, then I'd suggest that this be a schema validation/error then, instead of while compiling Java.
