SessionFactoryImpl is the default implementation of the SessionFactory interface. It is also responsible to init the SessionFactory.INSTANCE singleton. 

SessionFactoryImpl is currently a final class and session factory providers default way to provide their own factory is to copy the class and adapt it, then they miss the evolutions of the default factory, which might be acceptable for an internal class. 

I propose as a first step to update the factory and to remove the final modifier in order to allow other projects like Capella to begin to inherit form it instead of copying it. 
We might in later version move it from internal to api packages.
