Deserialization issues with Apicurio Avro Serdes (v2.6)

[ngc4579]

We're in the middle of evaluating the use of a schema registry in combination with a series of Kafka Streams applications based on Quarkus which implies we're currently bound to v2.6 Apicurio dependencies.

Is it generally a reasonable approach to have Avro Serdes auto-register schemas based on the Java classes used as Kafka Messages? As far as I understand, that should work using a reflective datum provider (ReflectAvroDatumProvider). In fact, schemas get successfully registered - but: deserialization fails with errors like this:

java.lang.NoSuchMethodException: java.util.UUID.<init>()

This originates from deserialization attempts for classes containing UUIDs like the following one:

public class SomeClass {
  private UUID id;
  private String someProperty;
  ...
}

Serde config:

Serde<T> serde = new AvroSerde<>();

serde.configure(
        Map.of(
                SerdeConfig.AUTO_REGISTER_ARTIFACT, true,
                SerdeConfig.REGISTRY_URL, registryUrl,
                SerdeConfig.ID_HANDLER, DefaultIdHandler.class.getName(),
                SerdeConfig.ENABLE_HEADERS, true,
                AvroKafkaSerdeConfig.AVRO_DATUM_PROVIDER, avroDatumProvider),
        false);

Seems I'm quite lost at the moment as I actually do not understand the root cause of the issue. How is this supposed to work at all? Or am I subject to fundamental misunderstanding here?

This is a new one on me. I'm not sure what's going on. Can you create a simple reproducer project? I can dig into it then.
