The ‘mamPrefsIq’ is:

<iq xmlns="jabber:client" from="swan@atalk.sytes.net" id="68GTJ-18" to="swan@atalk.sytes.net/atalk-5kd8p0" type="result">
    <prefs xmlns="urn:xmpp:mam:2" default="always">
        <always/>
        <never/>
    </prefs>
</iq>

Therefore the mamvVersion retrieval should be:

mamVersion = MamVersion.fromNamespace(mamPrefsIq.getChildElementNamespace());
