OpenJDK 9: Jshell - Using Swing / doing GUI stuff

After the posts buitin commands of jshell and how to load and save scripts i tried to get swing components running.

I created a script  HelloWorld.java
import javax.swing.*;       

JFrame frame = new JFrame("HelloWorldSwing");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JLabel label = new JLabel("Hello World");
frame.getContentPane().add(label);
frame.pack();
frame.setVisible(true);
But this does not work with Ubuntu:
jshell HelloWorld.java

Hmmm. This does look good.

On a Windows 10 host it works without any problem:


I hope this bug will be fixed soon...
EDIT: After downloading a new version from java.net it worked:

./java -version
java version "9"
Java(TM) SE Runtime Environment (build 9+178)
Java HotSpot(TM) 64-Bit Server VM (build 9+178, mixed mode)
