----------------------------------

             Summary: NPEs due to non-volatile Protocol variables
                 Key: JGRP-1871
                 URL: https://issues.jboss.org/browse/JGRP-1871
             Project: JGroups
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 3.4.5, 3.5
            Reporter: Paul Ferraro
            Assignee: Bela Ban


In WildFly a given channel is created in one thread, but is potentially started in a different thread.  Unfortunately, many of the protocol variables that are set during Protocol.init() are non-volatile. This can cause unexpected behavior as seen in WFLY-3727.
To ensure clean initialization for multi-threaded environments like WF, all non-final variables within every JGroups' Protocol should be volatile.
