Steve Shabino resolved AMQ-1716.
--------------------------------

    Resolution: Won't Fix

I realized that I could use the xbean-spring tools successfully.  Silly me.

> However, this does not work because the StorageUsage and TempUsage are never bound to
the persistenceAdapter or tempDataStore.

> One problem with this work-around is that old temp files are never purged as they would
be if I simply configured the temp directory via the BrokerService interface.  It would be
nice to have a more straight-forward means of configuring the BrokerService via Spring.
