试图在Fedora 23中运行JFLAP.jar.Java正在抛出异常

Question

Exception in thread "main" 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 gui.action.NewAction.showNew(NewAction.java:82)
    at gui.Main.main(Main.java:124)
    at JFLAP.main(JFLAP.java:57)

通过运行java -jar JFLAP.jar尝试运行JFLAP.jar文件时。它给了我上面的错误。运行java -version时它会告诉我：

openjdk version "1.8.0_71"
OpenJDK Runtime Environment (build 1.8.0_71-b15)
OpenJDK 64-Bit Server VM (build 25.71-b15, mixed mode)

关于出了什么问题的任何想法？感谢。
