I have a fresh install of Eclipse IDE for Java Developers that includes WindowBuilder and a few other packages.

I am trying to learn how to use WB and when I open a file with WindowBuilder Editor, the source tab looks fine, but if I click the DESIGN tab a progress window opens and then waits a short time and eclipse crashes.

I have tried simple files freshly created by eclipse as well as existing code.

The last time I got these messages, but they are not constant, so may just be noise
[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
java: ../../src/xcb_io.c:179: dequeue_pending_request: Assertion `!xcb_xlib_unknown_req_in_deq' failed.


The simple source file is

package myname;

import java.awt.BorderLayout;
import java.awt.EventQueue;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;

public class MainFrame extends JFrame {

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private JPanel contentPane;

	/**
	 * Launch the application.
	 */
	public static void main(String[] args) {
		EventQueue.invokeLater(new Runnable() {
			public void run() {
				try {
					MainFrame frame = new MainFrame();
					frame.setVisible(true);
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		});
	}

	/**
	 * Create the frame.
	 */
	public MainFrame() {
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setBounds(100, 100, 450, 300);
		contentPane = new JPanel();
		contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
		contentPane.setLayout(new BorderLayout(0, 0));
		setContentPane(contentPane);
	}

}


I also added a couple of screenshots as well

Any suggestions to get more specific details on why this is crashing?
This is really weird since this is a standard install!

I'm having the exact same issue, WindowBuilder was working fine until I updated from Ubuntu 15.04 to 15.10, and I suspect it has something to do with 32 bit vs 64 bit java. Have you looked into that at all?

I installed the Oracle Java and it worked fine.

Windows Builder does not seem to like OpenJDK

Sounds like that version of OpenJDK is buggy. Use Oracle Java or wait for the inevitable OpenJDK fix. I don't see anything here that indicates a bug in WindowBuilder itself.
