> The {{OakDefaultComponents}} inside the {{Oak}} builder class was introduced 
> with OAK-6826 and provides a set of default components. Those components can 
> be overridden by calling the various {{Oak.with()}} methods.
> There is a problematic {{OakDefaultComponents}} singleton {{INSTANCE}} used 
> by {{Jcr}}. The singleton is mutable and may leak modifications from one 
> {{Jcr}} instantiation to another one. More specifically, the 
> {{SecurityProvider}} has a couple of configurations that extend 
> {{ConfigurationBase}} with multiple setters.
