There is a design flaw in the ClassValue, the only way to initialize it is by ClassValue::computeValue(Class<?>).
It has been designed to attach some value to a class, however if your value needs some arguments to be computed, you need to attach them to the class, which you cannot. So it is a Catch-22.
