      Description

      trouble shooting http://fusesource.com/issues/browse/MB-668 causes the invocation of setMaxPageSize on a Destination from JMX that resulted in the broker dispatch loop getting into a state where it thinks there is nothing to dispatch. This needs to be resolved so that this situation cannot occur again.

            There have been improvements (from other unrelated issues) to the logic in doPageIn Queue.java such that the negative toPageIn count will no longer occur in the event of a concurrent change to the max page size.
