Why isn't a qualified static final variable allowed in a static initialization block?

Case 1

class Program {
    static final int var;

    static {
        Program.var = 8;  // Compilation error
    }

    public static void main(String[] args) {
        int i;
        i = Program.var;
        System.out.println(Program.var);
    }
}

Case 2

class Program {
    static final int var;

    static {
        var = 8;  //OK
    }

    public static void main(String[] args) {
        System.out.println(Program.var);
    }
}

Why does Case 1 cause a compilation error?

The JLS holds the answer (note the bold statement):

Similarly, every blank final variable must be assigned at most once; it must be definitely unassigned when an assignment to it occurs. Such an assignment is defined to occur if and only if either the simple name of the variable (or, for a field, its simple name qualified by this) occurs on the left hand side of an assignment operator. [§16]

This means that the 'simple name' must be used when assigning static final variables - i.e. the var name without any qualifiers.
