	This happens with the regular v1.2.1 jar (before the latest fixes). A user got this exception on screen: I don't know the scenario, it was during a regular usage of the FlowChart.

	drawShadows is implemented like this - Code private void drawShadows(Graphics2D g, Rectangle2D rc, boolean exclModf) { // iterate all types of items for (Item item: zOrder) { Rectangle2D rcObj = item.getRepaintRect(false); if (!rcObj.intersects(rc)) continue; if (!(exclModf && item.getModifying())) item.draw(g, true); } } You can get such exception if you delete a flowchart element while this method executes, either from a second thread or from some custom-draw event handler.

	I have a command chart.clearAll() that may be responsible for the items removal. The problem is that I can't control if another thread refreshes the flowChart or not during that time. Shouldn't the exception be caught and the method abandoned if this happened? In that case it is ok to fail repaint.
