Install4j JRE Bundle安装报错：启动路径不可访问及JDK检测异常

• 在MacOS环境运行Install4j安装程序时，无法检测到通过Sdkman安装的OpenJDK 21，因此会从私有Web服务器下载macos-amd64-21.0.1.tar.gz文件
• 下载完成后，安装程序将其解压到临时随机目录，但尝试启动时抛出**"launch path not accessible"（启动路径不可访问）**错误
• 运行debug_installer.sh未发现问题，推测未执行JRE相关初始化步骤
• 预期行为：安装程序能正常检测已安装的JDK；无可用JRE时自动下载并完成安装启动

更新：已定位报错原因——MacOS版JRE的tar.gz压缩包根目录缺少Contents文件夹
