xStream ForbiddenClassException followed by Axon Connector Converter error

Now that I have 3 microservices [ Product Service ] → [ CORE ] ← [ Order Service ]
Two services has he [ CORE ] as a dependency

I tried to dispatch a command from the the [ Core ] package but I’m getting ForbiddenClassException from commandGateway.send(Command)

com.package.app.order-service

@Saga
public class OrderSaga {
    @Inject
    private transient CommandGateway commandGateway;

    @StartSaga
    @SagaEventHandler(associationProperty = "orderID")
    public void handle(OrderCreatedEvent orderCreatedEvent) {

        commandGateway.send(new ReserveProductCommand(...), (commandMessage, commandResultMessage) -> {
            if (commandResultMessage.isExceptional()) {
                //Start compensating transaction
                LOGGER.error("- SAGA COMMAND ERROR "+commandResultMessage.getPayload());
            }
        });
    }

This is the one I’m not picking
com.package.app.product-service.CreateProductAggregate

@CommandHandler
public void handler(ReserveProductCommand reserveProductCommand) {
    LOGGER.info("+ ProductCommandHandler "
            + this.productID + " " + this.quantity + " " + reserveProductCommand);
    
    AggregateLifecycle.apply(new ProductReservedEvent(...));
}
@Configuration
public class ConverterConfig {
    @Bean
    @ConditionalOnBean(Converter.class)
    @Autowired
    public Collection<Converter> converters(XStream xstream, Collection<Converter> converters) {
        converters.forEach(converter -> xstream.registerConverter((com.thoughtworks.xstream.converters.Converter) converter));
        return converters;
    }
}
@Configuration
public class Config {
    @Bean
    @ConditionalOnMissingBean(XStream.class)
    public XStream xStream() {
        XStream xStream_ = new XStream();
        xStream_.addPermission(PrimitiveTypePermission.PRIMITIVES);
        xStream_.allowTypesByWildcard(new String[]{
                "org.axonframework.**",
                "com.mypackage.app.core.**",
        });
        return xStream_;
    }
}

I’ve created the configuration for xStream and I’m getting this error

I don’t understand the @ConditionalOnMissingBean(XStream.class) does it work if you remove it?
