Arkadiusz Gasinski commented on BEAM-13526:
-------------------------------------------
So I built a version of the Java Kafka IO SDK where I added a public modifier
to the DeserializerProvider interface and it worked like a charm, that is no
IllegalAccessError and I was able to deserialize incoming messages by means of
the ConfluentSchemaRegistryDeserialzerProvider class.
Shall I raise a PR with the public modifier added to the interface definition,
or there's more to the story that I'm not aware of?

> Key: BEAM-13526
> URL: https://issues.apache.org/jira/browse/BEAM-13526
> Project: Beam
> Issue Type: Bug
> Components: io-java-kafka
> Affects Versions: 2.34.0
> Reporter: Arkadiusz Gasinski
> Priority: P2
>
> I'm trying to configure my pipeline to read AVRO-encoded messages from Kafka
> with deserialization delegated to the
> ConfluentSchemaRegistryDeserialzerProvider, and I'm getting the following
> error:
> Exception in thread "main" java.lang.IllegalAccessError: failed to access
> class org.apache.beam.sdk.io.kafka.DeserializerProvider from class MyClass
> (both are in unnamed module of loader 'app')
> The way I configure the KafkaIO.Read is like:
> {code:java}
> KafkaIO.read<String, GenericRecord>()
> .withBootstrapServers(...)
> .withKeyDeserializer(StringDeserializer::class.java)
>
> .withValueDeserializer(ConfluentSchemaRegistryDeserializerProvider.of<GenericRecord>(...)
> .withTopic(...)
> ...{code}
> I checked the DeserializerProvider interface and it's package private - it's
> not even listed in the official java docs for Beam
> (https://beam.apache.org/releases/javadoc/2.34.0/org/apache/beam/sdk/io/kafka/package-summary.html);
> the ConfluentSchemaRegistryDeserialzerProvider is public.
> Am I the only one trying to use this API, or am I doing sth terribly wrong?
