Why Double.parseDouble("ABC") not returns Double.NaN?

This code:

Double.parseDouble("ABC")

throws a NumberFormatException.

Why is it wrong to expect a Double.NaN (NaN is literally Not-A-Number).

A working example is this:

public static void main(String[] args) {
    System.out.println("Is ABC a number? " + Double.isNaN(Double.parseDouble("ABC"));
}

I expect Is ABC not a number? true as output.

Why must this be an Exception?
