---------------------------------------

I have fixed Pedro's test to use the new Configuration API and remove useless code:

> I think I've spotted a issue when I use repeatable read with write skew check and I preload the cache.
>  
> I've made a test case to reproduce the bug. It can be found here [1]. 
> The problem is that each keys preloaded is put in the container with version = null. When I try to commit a transaction, I get this exception:
>  
> {code}
>  java.lang.IllegalStateException: Entries cannot have null versions!
