The whole idea is _avoid_ doing just that. Synchronizing the map locks the 
whole map on each call, a concurrent version would be thread-safe but not lock 
the whole map. Also, synchronizing the whole map still does not fix 
BEANUTILS-509, see that ticket.

As we already have a WeakHashMap: Can't one simply use 
Collections.synchronizedMap(weakMap)?
