----------------------------------------------------------

The underlying issue was the tracked last recovered priority. This needed to be reset in the
presence of newly added higher priority messages.
Fix and updated tests in http://git-wip-us.apache.org/repos/asf/activemq/commit/eece28ac

> With priority message enabled a batch of low priority messages can leave the cursor unable
to load subsequent high priority messages.
> More visible when useCache=false.
> A new consumer or browse will not be able to see pending messages.
> Issue occurs after dispatch of low priority messages, an empty store and the addition
of high priority messages.
