That's one way of solving it.

But AdvancedCache::with(CL) already solves this problem - that's why I used it (I remembered later :-)).

Where I think the two: AC::with(CL) and ServiceModuleLoader impl of ClassResolver, should no be connected.
Since they solve diff problems, imo.

Anyway, I'm now gonna try and hunt down where plain ML impl of CR somes in ...
