you have to use -Djava.awt.headless=true from your command line.

It seems your application needs some Xserver resources : maybe you are generating images or stuff like that. https://docs.oracle.com/javase/7/docs/api/java/awt/HeadlessException.html Maybe you should run in headless mode : http://www.oracle.com/technetwork/articles/javase/headless-136834.html or install a graphic server (maybe just the libs iirc).
