Here more analysis!
I can see that the order is scambled.
But this has nothing to do with the ordered load of the messages. It has to do with updating the Page_ORD.
The above error can be reproduced if you kill the server before all Page_Ord`s are updated.
So before UpdatePageOrderRunner().executeWithRetry(); finishes.
Then I see in my database this!
| ORD numbers not real numbers
| ORD PAGE_ORD
| 1 NULL
| 2 NULL
| 24 NULL
| 25 25
| 26 26
| 84 84
| 85 NULL
| 86 NULL
| 115 NULL
As you can see after Ord 85 the page_ord was not yet set!
Then I restart the server and while starting the QueueService the load() method is called. This results in calling loadFromStart() at the JDBC PersistenceManager.
I don't know why but after the first call it loads 50 unpaged messages to the Queue(pageOrd=NULL) and updated one (the last one) to 85. ?!?
So the ord message 115 has now page_ord 85.??
Then I stopped debugging.
So it seams that setting the right page_ord numbers is not handled well if the system has not set the numbers for the newest messages!
Hope this helps to reproduce the Bug
