Andrey Pavlenko commented on HARMONY-4647:
------------------------------------------

This demo does not work on Hrmony because it depends on RI's internal classes. To run this demo on Harmony replace the method clearImagesCache() with the following:

    private static void clearImagesCache() {
        try {
            if(clear == null) {
            	Class c = Toolkit.getDefaultToolkit().getClass();
            	Field cacheField = c.getDeclaredField("imageCache");
            	cacheField.setAccessible(true);
                softCache = cacheField.get(null);
                clear = softCache.getClass().getMethod("clear", null);
            }

            clear.invoke(softCache, null);
        } catch(Exception e) {
            System.out.println("unexpected: " + e);
            System.exit(-1);
        }
    }

With the above patch this demo runs on Harmony, but it does not produce any results - OOME occurs.
