Bug 87826 Need to improve image loading in Workbench
The Workbench image loading has several issues 1) The string "icons/full" is all over the place in the UI and should be made a constant 2) This needs to be prepended by /nl 3) The plugin descriptor is still in use to load images. This does not support nl which is required for BIDI support

String iconPath = "icons/full/";

            AbstractUIPlugin plugin = (AbstractUIPlugin) Platform
                    .getPlugin(PlatformUI.PLUGIN_ID);
            URL installURL = plugin.getDescriptor().getInstallURL();
            URL url = new URL(installURL, iconPath + relativePath);
            return ImageDescriptor.createFromURL(url);

            return null;
