Smack-4.2.3 - Unexplained Exceptions thrown by smack on various conditions

Smack Smack Support
1

Received the following unexplained smack exceptions log. Not sure why case #1 occurs when aTalk is exited. It happens on Note 3 and can be repeated with the same result.

case #2 happens on Note-8 when trying to remove earlier subscribed contact (aaa123). Not sure why the exception is not thrown upon receiving the <\present> stanza but only when contact is removed @26 mins later. then callConnectionClosedOnErrorListener.

case #3:
on Note-8, it receives both the returned subscribe and subscribed stanza from aaa123. However smack does not trigger upper level to take action on the the 2 returned subscribed and subscribe request. Next ping from Note-8 triggers the exception.

The problem occurs while performing Presence Subscription test as described in
https://github.com/processone/ejabberd/issues/2352#issuecomment-377146175 (last comment)

Appreciate some assistance on what can be the causes.
