Unable to calculate webservices port, using default 8080 message logged in JBoss EAP 6.

Issue

• When deploying an application, the webservices are deployed on default port 8080, although the domain.xml points to port 17501 (https). What I see in the logs is :

20160330:105816.151   [MSC service thread 1-8] DEBUG org.jboss.ws.common.management - JBWS022053: Unable to calculate webservices port, using default 8080

It looks like this is causing the wrong port number issue that I observe. Do you know why I get this message?
- After configuring the following in domain.xml :

   <subsystem xmlns="urn:jboss:domain:webservices:1.2">
                <modify-wsdl-address>true</modify-wsdl-address>
                <wsdl-host>${jboss.bind.address:127.0.0.1}</wsdl-host>
                <wsdl-port>17501</wsdl-port>

we can see the following wsdl:

....
<wsdl:service name="ReportItemWsFacadeService">
    <wsdl:port binding="tns:ReportItemWsFacadeServiceSoapBinding" name="ReportItemWsFacadeServicePort">
      <soap:address location="http://localhost:17501/autssreporting-webservice/ReportItemWsFacadeService"/>
    </wsdl:port>
  </wsdl:service>
......

As you can see the url is http and not https but it is using the configured http port. I conclude the bug is caused by webservice stack which is assuming http communication even if only the https connector is configured.
