Christopher L. Shannon commented on AMQ-7015:
---------------------------------------------

No problem, I was just pointing out he wasn't -1 so we can just leave it as for 
the 5.15.5 release because you guys feel strongly about it.

And I don't want to get into a big long thing about this so this is the last 
thing I will say....yes they are users and sure their opinion counts of course. 
 But since I've been part of the community for the past 3-4 years it has been 
pointed out numerous times that the community is everyone and more than one 
vendor.  So I agree their opinion counts but strongly disagree that based on 
that you can make a blanket statement and say there is "community support" 
without anyone else's opinion.  (Although you could probably make the argument 
that there is lazy consensus since no one said they disagree)

> I have a KahaDB that's performing a recovery on each startup.
> Digging deeper into it I've found that the issue is that the db.log contains 
> prepared transactions.
> The MessageDatabase will discard those entries in memory, however it does not 
> remove transaction info from those messages (I believe that's by design). So 
> on each restart, the broker will find those entries and again discard them in 
> memory.
> If I access the broker via JMX, I can go to the prepared XAs and execute a 
> clear on them one by one.
> When i restart my broker, i don't have a recovery attempted again.
> Performing a remove operation for each message can be very time consuming, so 
> i'd like to introduce an optional parameter to allow all prepared XAs to be 
> removed on recovery.
> Please see my forth coming patch with unit test.
