今天我将我的 Netbeans 6.8 更新为新的 Netbeans 7.4 并将 JDK 1.7.0 更新为 1.7.0_45 当我在新的 Netbeans 版本上打开我以前的项目时，sysnthetica 的外观和感觉 无法正常工作:( 其他一切正常:)
try {
UIManager.setLookAndFeel(new SyntheticaBlackStarLookAndFeel());
new frm_login().setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
这是错误:

提前致谢!
最佳答案
很可能您正在使用不支持 JDK 1.7 的 Synthetica 版本。下载最新的 Synthetica，你应该可以运行了
