The AppContext usage looks okay but I worry that changing this method to 
synchronized will lead to contention. At least for the non security 
manager then can this be changed so that the defaultPresentationManager 
is initialized via a holder class and changed to volatile and 
initialized via the usual double checked locking idiom. There are other 
options but I think this one is the important case and should not be 
synchronized.
