In this test the source of the appcontext (trayIcon) is deleted via an actionPerformed listener, so probably the deletion of the trayIcon comes first then the mouseEvent is trying to be posted onto the trayIcon and throwing an error

if the SunToolkit.executeOnEventHandlerThread is removed, then the test doesn't throw an exception, but the icon doesn't disappear (test fails)
