swagger2feature do not see javadocs ?

[Vjacheslav V. Borisov]

Hi!

Playing with
https://github.com/apache/cxf/tree/master/distribution/src/main/release/samples/jax_rs/spring_boot

Added Javadoc  to method sayHello

    /**
     * sayHello doc
     * @param a the a param
     * @return
     */
    public String sayHello(String a) {
        return "Hello2 " + a + ", Welcome to CXF RS Spring Boot World!!!";
    }

And do not see this documentation  in swagger.json / api-docs

Is javadoc parsing  not implemented in swagger.json generation, or i am
missing some switch?
