Parsing exception when receiving ad-hoc command answer

Hi Christian,

Using ad-hoc commands to get some information from my XMPP server I faced an XML parsing issue. The command which is sent is:

11:52:34.225 [WebSocket send thread] DEBUG c.a.c.c.babbler.XmppTrafficLogger - OUT: <iq xmlns="jabber:client" id="8f849dde-f4f1-46db-82c7-34e13988f1ab" to="sess-man@dc.ale-international.com" type="set"><command xmlns="http://jabber.org/protocol/commands" action="execute" node="http://jabber.org/protocol/admin#get-active-users-num" sessionid="get-active-users-num">
<x xmlns="jabber:x:data" type="submit">
<field type="hidden" var="FORM_TYPE"><value>http://jabber.org/protocol/admin</value></field>
<field type="list-single" var="domainjid"><value>dc.ale-international.com</value></field></x></command></iq>

The answer from the server is:

<iq to="admin@dc.ale-international.com/2145852718-tigase-116151" type="result" from="sess-man@dc.ale-international.com" id="669d3b2b-99eb-4ecd-b42c-3285c23fc423"><command status="completed" xmlns="http://jabber.org/protocol/commands" node="http://jabber.org/protocol/admin#get-active-users-num"><x xmlns="jabber:x:data" type="result"><field var="activeusersnum" type="fixed" label="The number of active users"><value>1</value></field></x></command></iq>

This answer raises an exception:

12:08:07.068 [ tyrus-jdk-client-3] ERROR c.a.c.client.babbler.LoginExecutor - Session error

The (approximate) English translation for [élément inattendu (URI : "", local : "iq"). Les éléments attendus sont] is [unexpected item (URI : "", local : "iq"). The expected items are].
