Hello.

I would like to thank you for helping me solve the problem.

I investigated a little and found that the dependency that is missing is from the "org.reactivestreams" and (in pom.xml) the maven code to insert and resolve the dependency would be this:

          <dependency>

            <groupId>org.reactivestreams</groupId>

            <artifactId>reactive-streams</artifactId>

            <version>1.0.1</version>

        </dependency>

Hope this helps
