So, all of these 3 checks have to fail in order to be considered key inequality? Could you spell out clearly what is expected here? I am not sure if this compound condition is correct. As it is now, the copy must have different format(2nd condition) AND different encoding(3rd condition) AND (not equals AND not same hash code)(1st condition), in order to trigger the RuntimeException.
