Запуск приложения Spring Boot в WebSphere 9

У меня есть приложение Spring Boot с основным классом:

@SpringBootApplication
public class MyApplication extends SpringBootServletInitializer{

    public static void main(String[] args) {
        SpringApplication.run(MyApplication .class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application){
        return application.sources(applicationClass);
    }

    private static Class<MyApplication > applicationClass = MyApplication .class;
}

С gradle.build:

version '1.0'
// dependencies for command line
buildscript {
    ext {
        springBootVersion = '1.4.3.RELEASE'
        dependencyManagementVersion = '0.6.0.RELEASE'
    }

Когда я пытаюсь развернуть военный файл на WebSphere Application Server 9.0 Traditional, он запускается, но занимает очень много времени. Без файла войны сервер запускается и останавливается очень нормально, но с приложением сервер зависает.

Я что-то упускаю?

Спасибо за помощь!!
