Hazelcast Spring Boot java.lang.ClassNotFoundException

Я запускаю экземпляр hazelcast в своем приложении весенней загрузки.

Конфигурация Hazelcast

@Configuration
@EnableCaching
public class HazelcastConfig {
    @Bean
    public Config hazelCastConfig() {
        final Config config = new Config();
        config.setClassLoader(getClass().getClassLoader());
        config.setInstanceName("cache");
        return config;
    }

    @Bean
    public HazelcastInstance hazelcastInstance() {
        return Hazelcast.newHazelcastInstance(hazelCastConfig());
    }
}

И время от времени он терпит неудачу из-за исключения class not found, когда я вызываю свою конечную точку HTTP, которая запрашивает данные из карты hazelcast.

Пробовал с config.setClassLoader(getClass().getClassLoader()); в классе конфигурации hazelcast и без него - через некоторое время он терпит неудачу с той же проблемой ClassNotFoundException.

Почему Hazelcast не справляется с этой проблемой и как ее исправить?
