Mqtt-spy 无法打开

我正在尝试安装 mqtt-spy，但它就是打不开。我已经安装了 java8 和 java9，当我使用命令时：

java -jar mqtt-spy-0.5.4-jar-with-dependencies.jar

这是我得到的输出：

就是这样，什么都没发生。我是 Ubuntu 的新手，所以我不知道是什么原因造成的。

我也有同样的问题。当我运行这个时，用户界面从未显示出来

java -jar mqtt-spy-0.6.0-beta-b52-jar-with-dependencies.jar

我尝试了mqtt-spy-0.5.4-jar-with-dependencies.jar和mqtt-spy-1.0.0.jar。

在 Ubuntu 16.04 LTS 上安装 OpenJDK 1.8.0_131 软件包后，它们可以正常启动openjfx。建议在维基页面。
