Ok,

I enabled DEBUG logging on the broker, and now I see this on restart:

2008-02-10 03:52:43,645 [127.0.0.1:64511] DEBUG RecoveryListenerAdapter       
- Message id ID:szjrosenberg-mbp17.local-64382-1202633445267-0:22:1:1:1
could not be recovered from the data store - already dispatched

In fact, I see 8 of these, and the webconsole in this case now shows '8'
pending messages for the queue, but never delivers them.  The webconsole
showed 0 pending messages before shutting down, etc...

I guess there are 2 issues.  First, if it can't recover the message, it
probably shouldn't show it as pending.   Second, need to find out why it's
even trying to recover the message in the first place, after showing no
Pending message before shutdown.

I'm using a 5.1-SNAPSHOT broker that I downloaded around Jan 24, 2008....
