Is it possible to lock the aspect ratio of a JFrame in Java Swing?

For example, if my window is 200px by 200px, and the user wants to resize it, I want the ratio between the width and the height at 1:1, so that if the new width is 400px, the new height is forced to 400px.

I'm aware of ComponentListener and componentResized, but I'm having difficulty not getting it to go into an infinite loop of resizing, because I'm resizing the window in a resize listener.

Thanks!
