Spring WebFlux and MVC config in the same library - spring

Question

I'm looking for a way to implement a "switch" in my library so that it would be able to work in 2 modes - reactive and blocking.
As of now i have two libraries doing basically the same thing - set of filters and interceptors and a factory providing end user with preconfigured WebClient/RestTemplate, Authentication and Authorization.
I found that SpringApplication.setWebApplicationType(WebApplicationType.REACTIVE) is supposed to force application to run in either a reactive or an mvc mode. However, when i add mvc-dependency i can see in log that Tomcat is being chosen as a container to run the app
Starting service [Tomcat]
Here's my pom.xml
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.0.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
And the Application class
#SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication app = new SpringApplication(Application.class);
app.setWebApplicationType(WebApplicationType.REACTIVE);
app.run(args);
}
}
Am i doing something wrong or the property is not supposed to allow switching between Netty and Tomcat to start with?
