У меня есть служба, которая потребляет поток целых чисел, созданных другим микросервисом через WebClient (org.springframework.web.reactive.function.client.WebClient), и время от времени встречается с приведенным ниже исключением. Что может быть причиной этого?

Таким образом, возможная причина может заключаться в том, что пакеты данных были повреждены до того, как они поступили на сторону клиента для распаковки. С Нетти не должно быть ничего плохого.
