安装NetBeans后Windows10中uniCenta oPOS无法启动的问题及解决

此前安装依赖JRE的收银系统uniCenta oPOS运行状态正常，为开发该系统源码安装带JDK的NetBeans后，uniCenta oPOS无法启动。尝试卸载重装NetBeans、JRE及uniCenta均无效，在CMD窗口运行jar文件时出现如下报错日志：

该程序在其他电脑可正常运行。

解决方案 #

• 问题根源：Windows10设备中同时安装了多个Java版本（8、17、19）及JRE、JDK，存在版本冲突。
• 修复步骤：
  1. 通过Windows10的「应用和功能」卸载所有Java相关组件
  2. 重装适配uniCenta oPOS的JRE，系统即可正常启动
• 注意事项：若需同时使用NetBeans开发与uniCenta oPOS，需确保JDK与JRE版本兼容。
