Java 11 Spring Boot java.lang.ClassNotFoundException: com.sun.xml.ws.api.server.SDDocumentSource$3

Question

Just to repoduce the issue I generated new project using Spring Initializr and I added jax-ws dependencies to pom.xml:

        </dependency>
    </dependencies>

    <build>
        <plugins>

                <configuration>

            </plugin>
        </plugins>
    </build>

</project>

And here is the main class:

@SpringBootApplication
public class JaxwsSpringBootJava11Application implements CommandLineRunner {

    public static void main(String[] args) {
        SpringApplication.run(JaxwsSpringBootJava11Application.class, args);
    }

    @Override
    public void run(String... args) throws Exception {
        Class<?> clazz = Class.forName("com.sun.xml.ws.api.server.SDDocumentSource");
        System.out.println(clazz);
    }
}

It works fine if run it with IntelliJ IDEA or mvn spring-boot:run. But it fails if build an executable jar with maven and run it:

mvn clean package
java -jar target/app.jar

I tried to do same with maven-assembly-plugin and it works. Maven version is 3.6.0. Here is the demo project to download: https://mega.nz/#!a9R1nQrS!RAhDKCYxiKNoy3TSazH-Jzak1k4b61EYaFAVEvYxFmY Here is logout:
