java.awt.HeadlessException从Kotlin REPL启动JavaFX应用程序

嗨，我试图从Kotlin的REPL启动一个简单的JavaFx应用程序来显示图表。 启动应用程序的代码很简单，但我得到了一个 java.awt.HeadlessException at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:204) at java.awt.Window.<init>(Window.java:536) at java.awt.Frame.<init>(Frame.java:420) at javax.swing.JFrame.<init>(JFrame.java:233) at com.github.lwhite1.tablesaw.plotting.fx.FxPlot.getJfxPanel(FxPlot.java:13) at com.github.lwhite1.tablesaw.api.plot.Pareto.initAndShowGUI(Pareto.java:65) at com.github.lwhite1.tablesaw.api.plot.Pareto.lambda$show$1(Pareto.java:41) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:311) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:756) at java.awt.EventQueue.access$500(EventQueue.java:97) at java.awt.EventQueue$3.run(EventQueue.java:709) at java.awt.EventQueue$3.run(EventQueue.java:703) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:76) at java.awt.EventQueue.dispatchEvent(EventQueue.java:726) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:201) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:116) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:105) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:101) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:93) at java.awt.EventDispatchThread.run(EventDispatchThread.java:82) 谷歌搜索，我发现参考这个命令，我跑了： System.setProperty("java.awt.headless", "false") 真正 但问题仍然存在，我使用Swing获得相同的错误。 我怎样才能从REPL显示GUI对象？ 谢谢。
