Кто понимает вообще, в чем дело? Подскажите, куда капать.

В логах рэббита ошибка в этот момент есть

[warning] <0.24281.300> closing AMQP connection <0.24281.300> 
(127.0.0.1:47278 -> 127.0.0.1:5672):
client unexpectedly closed TCP connection

Метод отправки события в рэббит

public static void sendEventToRabbit(BpmEvent event) {
    ObjectMapper mapper = new ObjectMapper();
    ConnectionFactory factory = new ConnectionFactory();
    factory.setHost("localhost");
    try (Connection connection = factory.newConnection();
         Channel channel = connection.createChannel()) {
        String message = mapper.writeValueAsString(event);
        channel.basicPublish(EXCHANGE_NAME, QUEUE_NAME, null, 
    message.getBytes("UTF-8"));
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (TimeoutException e) {
        e.printStackTrace();
