			IMPORTANT!!!

			The following instanceof checks and castings are intentional.

			DO NOT REFACTOR to make calls through the EntityEntryFactory interface, which would result
			in polymorphic call sites which will severely impact performance.

			When a virtual method is called via an interface the JVM needs to resolve which concrete
			implementation to call.  This takes CPU cycles and is a performance penalty.  It also prevents method
			in-ling which further degrades performance.  Casting to an implementation and making a direct method call
			removes the virtual call, and allows the methods to be in-lined.  In this critical code path, it has a very
			large impact on performance to make virtual method calls.
