There are at least couple of places where images are referenced using full path.
At least
   DragHelper has
¿ URL logoURL = ClassLoader.getSystemResource("sun/plugin/util/JavaCupLogo-161.png");
and
   ErrorPanel has reference on graybox_error.png

First problem cause DragHelperTest to hung on Solaris. This needs to be fixed and we need to validate that for all images that were renamed we do not have other references to them.
