TO REPRO:
With JDK1.2 beta3-J, execute SwingSet and click on the "ToggleButtons" or "RadioButtons" tab.

Move the mouse to the right-most Duke and wait until tooltip appears, now move mouse over to the Duke in the middle and wait until tooltip appears for that. Slowly move the mouse so that it is over the rectangle formed by the tooltip - app will terminate abruptly with dump below. It may not happen the first time, but keep at it and it will happen.

I've only gotten it to happen on Solaris only and not on win32, so it might just be a native thing.
