Can't lunch any tool on fedora 27

bluerose
I searched for solutions on the forum and I can't see any answers.
I have java installed on my computer version 1.8.0.
I run chmod x+u on .sh files.
I get this error messege:
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 java.awt.Frame.<init>(Frame.java:385)
        at javax.swing.JFrame.<init>(JFrame.java:189)
        at HackGUI.ControllerComponent.<init>(Unknown Source)
        at SimulatorsGUI.HardwareSimulatorControllerComponent.<init>(Unknown Source)
        at HardwareSimulatorMain.main(Unknown Source)

after that when i hit enter i get to prompt again.

By default Fedora installs headless Java. This means without any GUI stuff. Just yum install the full JRE and you're good to go.
