Adapter - Messaging - RabbitMQ - Pattern Matching for instanceof

[valentinajemuovic]

          @eamtalu, you can use the feature "Pattern Matching for instanceof" (JEP 394) here, so you won't need to make the casting, following the example and documentation:

if (eventDto instanceof AccountOpenedDto accountOpenedDto) {
    System.out.println(accountOpenedDto);
}
