I am implementing a xmpp client on Android, here is some issue I've noticed in MUC module
1. org.jivesoftware.smackx.muc.packet.MUCItem.toXML()
It doesn't check when 'role' is null. So when I tried to add a user to owner list, my app crashed.
2. org/jivesoftware/smackx/muc/MultiUserChatManager.getMultiUserChat()
It doesn't check null for multiUserChats.get(jid), which causes a NPE.
Hope this get fixed ASAP.
