-------------------------------------------------
Fix Version/s: 1.12.0

> 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
> Fix For: 1.12.0
>
> Time Spent: 10m
> Remaining Estimate: 0h

> 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:
> {code:java}
> [INFO] -------------------------------------------------------------
> [ERROR] COMPILATION ERROR :
> [INFO] -------------------------------------------------------------

> 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.
>
> NOTE: This is not unique to my/my company's use case - someone on SO also hit
