> Can't redefine classes with 1.12.0
> ----------------------------------
>
> Key: AVRO-4071
> URL: https://issues.apache.org/jira/browse/AVRO-4071
> Project: Apache Avro
> Issue Type: Bug
> Affects Versions: 1.12.0
> Reporter: Andrea Bettich
> Priority: Minor
> Labels: pull-request-available
> Fix For: 1.12.1
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> Hello,
> We noticed that with the new 1.12.0 version it's not possible to redefine
> classes, which are identical and are defined in two different avro files.
> As we aren't sure if this is a bug or an unintentional feature in the
> versions before 1.12.0, we are submitting the issue here but feel free to
> close it if this not intended to work. But if it's not intended I'm open to
> contribute a fix to get this resolved.
> I created a reproducer to show the behavior:
> [https://github.com/andreabettich/avro-schema-reproducer]
> Failing job to show the error:
> [https://github.com/andreabettich/avro-schema-reproducer/actions/runs/11141772156/job/30963342027#step:4:1147]
> Based on the error message while generating, it fails at this check:
> [https://github.com/apache/avro/blob/80400781a796bc0e90dd8ea1db42234926db33e9/lang/java/avro/src/main/java/org/apache/avro/ParseContext.java#L219]
> When checking the values when you run the maven task, the values are the
> following:
> _schema:_
> {code:java}
> {
> "type" : "record",
> "name" : "SharedObject",
> "namespace" : "ch.mobi.oss.avro.external"
> }
> {code}
> _alreadyKnownSchema:_
> {code:java}
> {
> "type" : "record",
> "name" : "SharedObject",
> "namespace" : "ch.mobi.oss.avro.external",
> "fields" : [ {
> "name" : "number",
> "type" : "int"
> }, {
> "name" : "code",
> "type" : "int"
> } ]
> }{code}
> The record schema object is passed from here, which happens before adding the
> fields. So I assume that this should actually happend after adding the field,
> then it would work (didn't test it yet)

> Thanks for your work and hope we find a solution for the issue.
