There is a legacy app that uses swing, and it spawns various windows for various purposes at various times. What I'm wondering is if it possible to get a "screenshot" of each window, without having to actually go through the screenshot utility on my OS. I know this is possible somehow, but I'm wondering if it is something nicely supported by swing/java? I'd love to just load a file via this app, iterate over the windows spawned, and write an image out somewhere.

Sikuli is pretty neat, it allows you to automate anything, based on image recognition. Their site: www.sikuli.org. And it can take screenshot while running the automated task you scripted: How to take screenshot with sikuli
I'm not affiliate to sikuli whatsoever, I simply used it in the past (to automate tests on a swing GUI). The description on their site:
Sikuli automates anything you see on the screen. It uses image recognition to identify and control GUI components. It is useful when there is no easy access to a GUI's internal or source code.
