报错原因
（根据chatgpt的回答）
这个错误是由于 Java 9 及以上版本中，模块化系统的安全性增强所导致的。在 Java 9 及以上版本中，java.lang.ClassLoader.defineClass 方法默认不可访问，因此需要在模块化应用程序中显式地打开此方法的访问权限。
为了解决这个问题，可以尝试以下步骤：
- 在 Cerebro 启动命令中添加
--add-opens参数
在启动 Cerebro 时，可以通过添加 --add-opens 参数来打开 java.lang.ClassLoader.defineClass 方法的访问权限。例如，以下命令可以启动 Cerebro 并打开此方法的访问权限：
java --add-opens java.base/java.lang=ALL-UNNAMED -jar cerebro.jar
- 将 Cerebro 更新到最新版本
Cerebro 的最新版本已经修复了这个问题，因此可以尝试将 Cerebro 更新到最新版本，并再次尝试启动。最新版本的 Cerebro 可以从官方网站下载。
希望这些步骤能够帮助你解决 Cerebro 启动时出现的错误。
解决方法
将java的jdk版本改为JDK1.8即可解决报错
