Running Nashorn

[Jim Laskey (Oracle)]

Kasper,

It should work as is.  I regularly use Nashorn for shell scripting headlessly.

- Check to make sure you are using the latest JDK 8. There was a bug in ScriptManager that was fixed many releases ago.  http://jdk8.java.net/download.html
- Check to see if some other command line option is triggering the GUI.
- If you are using 'jjs', don't specify -fx.
- If you use an old version of JSObject, the Applet argument on getWindow will force a GUI.
- Check for other AWT / JavaFX references in your code.
- Check to see if you have other script engines installed that might trigger a GUI.

Cheers,

-- Jim
