> I was digging in the project deps and if you compare all libs in "libs" dir 
> and all libs in "build/lib/jars", there are indeed some diffrences which are 
> OK however in build/lib/jars there are also libraries for byteman and 
> byte-buddy. This is clearly wrong as these dependecies should not accessible 
> from the production code, only from tests.
> The reason they are accessible in prod code is that there is a class 
> TestRateLimiter (1). I do not have a clue why that class is in the prod code 
> in the first place. The only place it is referenced in is here (2) but that 
> byteman script is not loaded anywhere in tests. I was also checking Python 
> dtests.
> I think this is some leftover or something like "I will keep it here when I 
> need it", but as nobody seems to do, I strongly advocate for removing it and 
> making bytebuddy and byteman only test scoped dependencies as it should be.
> Second issue is that there is a dependency on compress-lzf in build 
> dependencies. This is not necessary either as that library was removed from 
> the repository in (3) but it still somehow leaked to the build process again.
