我刚刚安装了 NetBeans 8.2，一切似乎都进展顺利。我几乎 100% 按照默认设置操作，除了删除了一两个我永远不需要的模块，并在第一次运行时更改了默认工作区。
现在它什么都不做。当我点击命令时File->New Project，什么都没有发生。当我点击其他几个命令时，什么都没有发生。
在我尝试创建项目后，IDE 日志确实显示了堆栈跟踪。这是该跟踪：

请说明 jdk 版本。就我而言，我使用下一个解决方案：NetBeans 8.2 与 jdk 9 不兼容。我暂时重命名目录 jdk-9 并在重新启动时更改默认 jdkhome。或者在 etc\netbeans.conf 中更改 netbeans_jdkhome。
