Kafka Streams app on native build fails to read json process file

Describe the bug

When running a Kafka Streams native image app second time with an existing state directory, it fails to read the process file with the following exception:

Failed to read json process file: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of org.apache.kafka.streams.processor.internals.StateDirectory$StateDirectoryProcessFile (no Creators, like default constructor, exist): cannot deserialize from Object value (no delegate- or property-based Creator) at [Source: (File); line: 1, column: 2] at com.fasterxml.jackson.databind.DeserializationContext.reportBadDefinition(DeserializationContext.java:1764) at com.fasterxml.jackson.databind.DatabindContext.reportBadDefinition(DatabindContext.java:400) at com.fasterxml.jackson.databind.DeserializationContext.handleMissingInstantiator(DeserializationContext.java:1209) at com.fasterxml.jackson.databind.deser.BeanDeserializerBase.deserializeFromObjectUsingNonDefault(BeanDeserializerBase.java:1415) at com.fasterxml.jackson.databind.deser.BeanDeserializer.deserializeFromObject(BeanDeserializer.java:362) at com.fasterxml.jackson.databind.deser.BeanDeserializer.deserialize(BeanDeserializer.java:195) at com.fasterxml.jackson.databind.deser.DefaultDeserializationContext.readRootValue(DefaultDeserializationContext.java:322) at com.fasterxml.jackson.databind.ObjectMapper._readMapAndClose(ObjectMapper.java:4593) at com.fasterxml.jackson.databind.ObjectMapper.readValue(ObjectMapper.java:3413) at org.apache.kafka.streams.processor.internals.StateDirectory.initializeProcessId(StateDirectory.java:201) at org.apache.kafka.streams.KafkaStreams.<init>(KafkaStreams.java:805) at org.apache.kafka.streams.KafkaStreams.<init>(KafkaStreams.java:782) at org.apache.kafka.streams.KafkaStreams.<init>(KafkaStreams.java:692) at io.quarkus.kafka.streams.runtime.KafkaStreamsProducer.initializeKafkaStreams(KafkaStreamsProducer.java:156) …

When I inspect the org.apache.kafka.streams.processor.internals.StateDirectory, it seams the following fragment causes the problem:

            try {
                final StateDirectoryProcessFile processFileData = mapper.readValue(processFile, StateDirectoryProcessFile.class);
                log.info("Reading UUID from process file: {}", processFileData.processId);
                if (processFileData.processId != null) {
                    return processFileData.processId;
                }
            } catch (final Exception e) {
                log.warn("Failed to read json process file", e);
            }

I think, StateDirectoryProcessFile class being a package protected static inner class causes Jackson to fail when trying to create an instance of it within the native build to deserialize the process file.

I use quarkus-container-image-docker extension to build the native image. Docker file for the native image is the standard Dockerfile.native file which uses quay.io/quarkus/quarkus-micro-image:1.0 base image.

Sorry guys I forgot about this issue. I will gat right on it this week if thats ok.

FWIW, the syntax for a nested class is: org.apache.kafka.streams.processor.internals.StateDirectory$StateDirectoryProcessFile with a $.
