Not sure when exactly Java broke (I'm not using it much) but it worked before 
and now I get (when using a GUI program):

Does using a Java GUI "fat client" application work for you?

$ java -version
openjdk version "1.8.0_91"
OpenJDK Runtime Environment (IcedTea 3.0.1) (linux-gnu build 1.8.0_91-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

Note that I didn't install icedtea:jdk . I've since installed it into my user 
profile - no change.

Minimal example to reproduce:

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.WindowConstants;

public class A {
        public static void main(String[] args) {
                JFrame f = new JFrame();
                JLabel l = new JLabel("Hello");
                f.add(l); // comment me
                f.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
                //f.pack();
                f.setVisible(true);
        }
}

(breaks as soon as the label is in the frame)
