MUC服务不支持MUC配置'muc＃roomconfig_roomowners'

Question

我正在使用xmpp，我想创建群聊。当我尝试使用下面的代码创建组时，我收到以下错误：

MUC服务不支持MUC配置'muc＃roomconfig_roomowners'。

为什么我会收到此错误？任何人都可以帮我解决吗？

这是我的代码：

public void createGroupChat() {

    MultiUserChatManager manager = MultiUserChatManager.getInstanceFor(connection);
    try {
        EntityBareJid jid = JidCreate.entityBareFrom([email protected]);

        MultiUserChat muc = manager.getMultiUserChat(jid);

        Set<Jid> owners = JidUtil.jidSetFrom(new String[]{"abc@servicename", "xyz@servicename"});

        Resourcepart nickname = Resourcepart.from("nickname");
        muc.create(nickname).getConfigFormManager().setRoomOwners(owners).submitConfigurationForm();

    } catch (XmppStringprepException e) {
        e.printStackTrace();
    } catch (MultiUserChatException.MucAlreadyJoinedException e) {
        e.printStackTrace();
    } catch (InterruptedException e) {
        e.printStackTrace();
    } catch (XMPPException.XMPPErrorException e) {
        e.printStackTrace();
    } catch (MultiUserChatException.MissingMucCreationAcknowledgeException e) {
        e.printStackTrace();
    } catch (NotConnectedException e) {
        e.printStackTrace();
    } catch (SmackException.NoResponseException e) {
        e.printStackTrace();
    } catch (MultiUserChatException.NotAMucServiceException e) {
        e.printStackTrace();
    } catch (MultiUserChatException.MucConfigurationNotSupportedException e) {
        e.printStackTrace();
    }
}
