linux - 无法在 Linux 上使用 jxbrowser 创建新的浏览器

Question

我有一个在 Mac 上使用 jxbrowser 的小测试程序。我正在尝试在 Fedora 安装上运行测试程序，但无法获取浏览器对象的实例。

这是程序的日志记录。有谁知道什么会导致 jxbrowser 无法创建浏览器？

请确保您的 Linux 环境不是 headless 环境。 JxBrowser 不支持不运行 X 服务器的 headless linux 环境:https://jxbrowser.support.teamdev.com/support/solutions/articles/9000013733-system-requirements
