exception - something excepted; an instance or case not conforming to the general rule. An invalid argument parameter is certainly an exception. Human readable exceptions are a much better solution than the alternatives, such as return codes or returning null. What other solution would you propose? The only thing that could improve this even more is if the parameter named itself were visible, i.e. "buffer cannot be null" rather than "Value cannot be null"
