[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - Strange (?) code in transactionimpl for paging

[timfox]

  | // Putting back the size on pagingManager, and reverting the counters
  |          
  | 
  |          if (message.incrementReference(message.isDurable() && queue.isDurable()) == 1)
  |          {
  |             pagingManager.addSize(message);
  |          }
  | 

I don't understand why this code is necessary. Surely paging happens *before* routing.

So any cancellation shouldn't effect any counters. After all, after cancellation it doesn't get paged again, it's still routed.
