In Java, best way to check if Selenium WebDriver has quit

In Java, best way to check if Selenium WebDriver has quit

I need to check a collection of Page Objects to see, for each one, if
quit() has been called on its WebDriver.
I've written the following method to check a WebDriver's state:
public static boolean hasQuit(WebDriver driver) {
try {
driver.getTitle();
return false;
} catch (SessionNotFoundException e) {
return true;
}
}
I don't like having to throw and catch an exception to discover the truth
of a boolean, but it seems I have no choice since the WebDriver API
doesn't provide a method to check if the driver has quit.
So my question is, is there a better way to check if a WebDriver has quit?
I found a similar (and more general) question here, but the question did
not have any code that had been tried, and the only answer was to always
set the WebDriver to null after quiting (which I don't necessarily have
control over).
