UNICAST2: incorrect delivery order
----------------------------------

                 Key: JGRP-1267
                 URL: https://issues.jboss.org/browse/JGRP-1267
             Project: JGroups
          Issue Type: Bug
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 2.11.1, 2.12


Under stress, UNICAST2 can deliver messages in incorrect order. The reason is that in UNICAST2.handleDataReceived() 'processing' is set to false in the finally clause, no matter what. This can cause multiple threads to concurrently deliver messages for the same destination.

SOLUTION: copy the code from NAKACK.handleMessage(), which does *not* set 'processing' to false in finally
