Spring Boot 2.1.0 with Jersey - spring-boot

Question

Today i started a simple application spring boot application. Because i am starting from the scratch, i am using the latest version of SpringBoot: 2.1.0.RELEASE
I would like to use Jersey to use JAX-RS. I have this working for 1.3.6 Spring Boot version, but I am getting the following error:
***************************
APPLICATION FAILED TO START
***************************
Description:
The bean 'requestContextFilter', defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$WebMvcAutoConfigurationAdapter.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/boot/autoconfigure/jersey/JerseyAutoConfiguration.class] and overriding is disabled.
Action:
Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true
I can't understand where the problem could be because my application at this point is minimalist.
Apparently the bean 'requestContextFilter' is being configured twice but i have no idea where it is configured.
Here is my configuration:
pom.xml
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.0.RELEASE</version>
</parent>
<properties>

<start-class>pt.msoftware.userauthservice.App</start-class>
<java.version>1.8</java.version>
<docker.image.prefix>${user.name}</docker.image.prefix>
</properties>

SpringBoot application class
#SpringBootApplication
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
** Jersey Config**
import org.glassfish.jersey.server.ResourceConfig;
import org.springframework.stereotype.Component;
import pt.msoftware.userauthservice.rest.UserEndpoint;
import javax.ws.rs.ApplicationPath;
/**
* Created by marco on 31/10/2018.
*/
#Component
#ApplicationPath("/rest")
public class JerseyConfig extends ResourceConfig {
public JerseyConfig() {
register(UserEndpoint.class);
}
}
** Endpoint**
import org.springframework.stereotype.Component;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
/**
* Created by marco on 31/10/2018.
*/
#Component
#Path("/user")
public class UserEndpoint {
#GET
public String message() {
return "Hello";
}
}
Can someone spot what I am missing or what might be wrong with my code/config?
Thank you so much

It's a bug in Spring Boot. Thanks for bringing it to our attention. I've opened this issue to track the problem.
If you intend to only use Jersey and JAX-RS, you do not need to use spring-boot-starter-web. It's, essentially, a Spring MVC-based equivalent of spring-boot-starter-jersey. You can, therefore, avoid the problem you're seeing by removing the spring-boot-starter-web dependency from your application.
If you do want to use both Spring MVC and JAX-RS, you can enable bean definition overriding by adding spring.main.allow-bean-definition-overriding=true to your application.properties file in src/main/resources.
