Hi Deserialization problem

The current java-sdk API makes this a tad brittle, but the approach works for me:

    val mapper = ObjectMapper()

    // Configure the mapper just like the JacksonJsonPayloadConverter() constructor would
    mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false)
    mapper.registerModule(JavaTimeModule())
    mapper.setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY)

    // Now add Kotlin support
    mapper.registerModule(KotlinModule())

    // And build the exact same thing as DefaultDataConverter::defaultDataConverterInstance
    val converter = new DefaultDataConverter(
            NullPayloadConverter(),
            ByteArrayPayloadConverter(),
            ProtobufJsonPayloadConverter(),
            JacksonJsonPayloadConverter(mapper))

    // Now create a workflow client options with it, and move along as before!
    val workflowClientOptions = WorkflowClientOptions.newBuilder()
                .setDataConverter(converter)
                .build();
