> 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.
