Pass to Muc - > Chat normal XMPP (some problems, and not work correctly)

Goodnight,

So far we have used "muc" but e have seen that there is the issue offline "OfflineMessageManager" and the like, not related to "Muc".

We have gone from "muc" --to---> "http://www.igniterealtime.org/builds/smack/docs/latest/documentation/messaging.h tml"

There are some problems:

1 - If the 2 users are online (Thread), one of the two users can not send data to another user.

2 - Not all packets arrive, "the debugguer, you can see that the listener is called, but not access Print anything.

Muc Works 100 %

Any solution?
