Yep, seems to be the same bug... And it's happening _A_LOT_ on our 
production environment :-( :-(

Have you noticed, by any chance, a ConcurrentModificationException 
somewhere in your tests?

I noticed that the ExcaliburComponentManager doesn't correctly 
synchronize on its m_componentHandlers hashmap, and that might be the 
root of our problems...
