> Cannot validate schemas with recursive definitions
> --------------------------------------------------
>
> Key: AVRO-2122
> URL: https://issues.apache.org/jira/browse/AVRO-2122
> Project: Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.8.2
> Reporter: Bart
>
> Validating a schema with a recursive definition will lead to a stack
> overflow. When using the following schema definition:
> {noformat}
> @namespace("avro")
> protocol Unused {
> record Node {
> union { null, Node } value = null;
> }
> }
> {noformat}
> {code:java}
> final SchemaValidator backwardValidator = new SchemaValidatorBuilder()
> .canReadStrategy().validateLatest();
> backwardValidator.validate(Node.SCHEMA$, Arrays.asList(Node.SCHEMA$));
> {code}
> It results in a stack trace:
> {noformat}
> java.lang.StackOverflowError
