JmDNS Error - The method getInetAddresses() is undefined for the type ServiceInfo

Question

For some reason it doesn't like the getInetAddresses() method in the lines:

Enumeration additions = (Enumeration) ev.getInfo().getInetAddresses();
if (ev.getInfo().getInetAddresses() != null && ev.getInfo().getInetAddresses().length > 0) {
    additions =  ev.getInfo().getInetAddresses()[0].getHostAddress();
}

        jmdns.addServiceListener(type, listener = new ServiceListener() {

                Enumeration additions = (Enumeration) ev.getInfo().getInetAddresses();

            }
        });
        serviceInfo = ServiceInfo.create("_test._tcp.local.", "AndroidTest", 0, "plain test service from android");
        jmdns.registerService(serviceInfo);
    } catch (IOException e) {
        e.printStackTrace();
        return;
    }
}

Try download and use latest version of JmDNS from Maven Central Repository, apparently there are some issues related to the jar file downloaded from their SourceForge home page. jar file from SourceForge doesn't play quite nice with Android.
