How do I profile the EDT in Swing?

Question

I have an application that I\'m building in Swing. It has a scrollable and zoomable chart component which I can pan and zoom in. The whole thing is smooth except that sometime

I'd say it's likely this isn't actually something on the EDT but actually garbage collection.

Assuming that's the case I don't know of any solution I'm afraid. I've actually never written anything in Swing which didn't have this type of behavior occasionally.

To try & debug you could subclass EventQueue & install a new one using:

Toolkit.getDefaultToolkit().getSystemEventQueue().push(xxx);

This should allow you to at least see what events are being processed by the EDT.
