JAX-RS missing params (complex type) in request and response

Question

I'm using JAX-RS to create a WADL file. The main problem is that when using a complex type (Ergebnis) in the generated WADL file the details of the request are missing. When i change the complex types Ergebnis and Anfrage in simple types like String the output is as expected. My code can be seen below.

I had to massively reduce my code to describe my problem concise. Hopefully i didn't mess up and type some mistakes in it. I hope someone can help me.

@POST
@Path("/testpfad")
@Produces(MT_JSON)
@Consumes(MT_JSON)
@Descriptions({ @Description(value = "Testbeschreibung", target = DocTarget.METHOD) })
Ergebnis testMethod(@NotNull Anfrage anfrage)

@XmlRootElement
@Doc(value = "Beschreibung")
public class Ergebnis {

    @Doc("Beschreibung")
    private boolean test

    public boolean isTest() {
        return test
    }

    public void setTest(final boolean test) {
        this.test = test
    }
}

Anfrage is looking similar to Ergebnis.

Generated WADL file:
