org.jboss.mq.MessageStatistics needs to be extended to provide equivalent functionality to the listMessageCounterHistory() operation which is going away. The current listMessageCounterHistory() method returns the number of messages a topic/queue has received on each hour of each day. The number of days such information will be maintained is specified in the MessageCounterHistoryDayLimit property. We want to display similar information on the Admin Console, so what we need is probably a list of some data structure (i.e. MessageHistoryDayInfo), each containing the date and an array ([0:23]) with each element specifying the number of messages received on that hour.
