After I posted the previous message I learned more ,
and now I am about sure that the problem come from the graphic environment of Linux...
and now I am about sure that the problem come from the graphic environment of Linux...
After I Installed Fedora 27 I got to use a Wayland session of gnome, instead the usual X11 session :
if I do :
loginctl show session 2 -p Type,
I get
Type=wayland
instead that
Type=x11 (that is the value I get on computer where is Fedora 21)
Type=x11 (that is the value I get on computer where is Fedora 21)
Wyland is not good environment for running the graphical program that is used to install netBeans... (the .sh script)
So I am looking now how I can return to session X11 inside Gnome...

This is a problem about the java environment ?
it can be also a problem with the graphical environment of fedora ... (?)
An application running as root can't access the display when using Wayland.
