Java printing issue under Sierra 10.12.4

Hi,

Since the release of Sierra 10.12.4, the users of Sweet Home 3D sandboxed version can't print anymore.

This Java program simply hangs on the call to PrinterJob#printDialog under this system, but there's no problem on previous systems or when the program isn't sandboxed.

I isolated this issue in the following example that will hang also:

import java.awt.Graphics;
import java.awt.print.*;
import javax.swing.JOptionPane;

public class PrintTest  {
  public static void main(String [] args) {
    PrinterJob printerJob = PrinterJob.getPrinterJob();
    printerJob.setPrintable(new Printable() {
        public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {
          // Print one empty page
          return pageIndex == 0 ? PAGE_EXISTS : NO_SUCH_PAGE;
        }
      });
    JOptionPane.showMessageDialog(null, "setPrintable works!");

    if (printerJob.printDialog()) {
      try {
        printerJob.print();
        JOptionPane.showMessageDialog(null, "PrinterJob works!");
      } catch (PrinterException e) {
        JOptionPane.showMessageDialog(null, "PrinterJob exception: " + e);
      }
    }
  }
}

Entitlements are set as following:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-/
<plist version="1.0">
<dict>
  <key>com.apple.security.app-sandbox</key>
  <true/>
  <key>com.apple.security.files.user-selected.read-write</key>
  <true/>
  <key>com.apple.security.print</key>
  <true/>
  <key>com.apple.security.network.client</key>
  <true/>
</dict>
</plist>

Any suggestion why this could happen and how to fix it?

Thanks for your help,

Emmanuel
