      When cluster encryption is enabled, the log contains exceptions like

      [0m[31m18:49:07,295 ERROR [org.jgroups.protocols.TCP] (Incoming-2,shared=tcp) failed handling incoming message: java.lang.ArrayIndexOutOfBoundsException: -1

      it seems that ENCRYPT protocol in JGroups is deprecated and was replaced with SYM_ENCRYPT and ASYM_ENCRYPT - see https://issues.jboss.org/browse/JGRP-2088
      We need to find out if it was depracated/broken by design or if it violates our backwards compatibility policy.
