[Bug awt/32513] New: new gtk peer locking issues

[thebohemian at gmx dot net]

Hi,
one of the latest patches caused the evil gtk locking issues to reappear.

I cannot run the some simple Swing applications anymore.

Running this app:

import java.awt.event.*;
import java.awt.*;
import javax.swing.*;

public class SwingTest
{
  public static void main(String args[]) throws Exception
  {
    JFrame f = new JFrame("Test");
    f.setBounds(0, 0, 320, 240);
    JButton b;

    f.add(b = new JButton("Click me!"));

    b.addActionListener(new ActionListener()
    {
        public void actionPerformed(ActionEvent ae)
        {
          System.out.println("GoodBye!");
          System.exit(0);
        }
    });

    f.show();

    f.addMouseListener(new MouseAdapter()
    {
      public void mousePressed(MouseEvent me)
      {
        System.out.println("pressed: " + me);
      }

      public void mouseReleased(MouseEvent me)
      {
        System.out.println("released: " + me);
      }
    });
  }
}

I will get the window and the button but I cannot click it and repaints arent
done, too. The app is running with GNU Classpath-HEAD and Cacao. A forced
stacktrace (kill -SIGQUIT) gives:

Another application (this time bigger) for example
http://www.eigenheimstrasse.de/josm/josm-latest.jar hangs already inside the
ComponentGraphics::initstate() method on gdk_enter().
