HornetQ warning on startup for default configuration

Issue

• After starting to use JBoss-EAP-6.4 CP12 we see this warning when we start up our HornetQ servers and we are wondering if this is something we should worry about :

WARN [org.hornetq.core.server] (Thread-2 (HornetQ-server-HornetQServerImpl::serverUUID=aaaabbbb-cccc-dddd-eeee-1234567890-987654321)) HQ222192: The size of duplicate cache detection (<id_cache-size/>) appears to be too large. It should be no greater than the number of messages that can be squeezed into conformation buffer (<confirmation-window-size/>).
