    Deadlock in RosterItemProvider


      Hi all,






      I have an openfire plugin which launch cuncurrent threads to managed user roster.



      A problem raised during the test, a deadlock in the SequenceManager.next() method.



      The problem was fixed exchanging the order of












      in this way:



                  long rosterID = SequenceManager.nextID(JiveConstants.ROSTER);

                  con = DbConnectionManager.getConnection();



      The nextID method call the DbConnectionManager.getConnection() as well, then when there is no longer available db connection the thread block all db accesses.
