I've seen this in the past in the Rainbow demo that is part of Radiance (navigating the local disk structure with the breadcrumb bar), but can no longer reproduce this crash there. Do you have a way to reliably reproduce this in 3.5-SNAPSHOT in a small, standalone app?

I've seen this in the past in the Rainbow demo that is part of Radiance (navigating the local disk structure with the breadcrumb bar), but can no longer reproduce this crash there. Do you have a way to reliably reproduce this in 3.5-SNAPSHOT in a small, standalone app?

If you reproduce the problem, you can run the demo code: Check.java 。 After running the program, in the general settings, check the animation effect of icon rollover, and move the mouse to and fro on the toolbar. This exception will be thrown. Is it that after the animation is started, repeated for many times caused the thread to be out of sync?
