Details:

Open a terminal on a system without X and try to run


> octave --no-gui --no-window-system
octave:1> a = menu('title', {'a', 'b', 'c'})


This gives an error:


error: [java] java.awt.HeadlessException: 
No X11 DISPLAY variable was set, but this program performed an operation which
requires it.
error: called from
    listdlg at line 147 column 9
    menu at line 58 column 16


This is contrary to what the documentation for menu() says:
If the GUI is running, or Java is available, the menu is displayed graphically
using 'listdlg'.  Otherwise, the title and menu options are printed on the
console
