inline type is always value class, but the opposite is not correct (abstract value class is not inlined type)
The idea is any object's type is concrete class.
It's not important here as we check type of the existing object (i.e. we cannot get abstract class)
I updated the fix moving the functionality to ClassTypeImpl (still working on the test update)
