> Merge method is not correctly implemented in SimpleCache.
> Merge should work this way :
> * if the key is not present, add the value
> * If the key is present, apply the function between the existing key's value and the given value and replace the key with the merged result
> * If the merge function returns null, remove the key
> The case that should work as "putIfAbsent" does't work. Merge function is applied to null and the given value.
