今天我更新了我的新版本，Netbeans 6.8当Netbeans 7.4我在新版本上打开我以前的项目时无法正常工作:(其他一切工作正常:)JDK 1.7.01.7.0_45Netbeanssysnthetica look and feel

try {
UIManager.setLookAndFeel(new SyntheticaBlackStarLookAndFeel());                  

new frm_login().setVisible(true);
    } catch (Exception e) {
        e.printStackTrace();
    }

这是错误：

您很可能正在使用不支持 JDK 1.7 的 Synthetica 版本。下载最新的 Synthetica，您应该正在运行
