Subject	[platform-swt-dev] Too many ToolItems bug

I have found that when I create a certain number of ToolItems in a Toolbar
they will not display. I am compiling and running my code on a mac, OSX
10.4.10, JVM 1.5, with eclipse/SWT 3.2. In the code below if you set the
COUNT variable to 310 or lower, you will see the toolitems display correctly
- but if you set the COUNT to 311 or higher then you will not see the toolitems
at all. I have not stepped into the SWT source to see what is going on,
anyone have any ideas ? 

import org.eclipse.swt.SWT; 
import org.eclipse.swt.graphics.Image; 
import org.eclipse.swt.graphics.Point; 
import org.eclipse.swt.layout.FillLayout; 
import org.eclipse.swt.widgets.Display; 
import org.eclipse.swt.widgets.Shell; 
import org.eclipse.swt.widgets.ToolBar; 
import org.eclipse.swt.widgets.ToolItem; 

public class ToolbarTest 
{ 
        private static final int SIZE = 100;
        
        private static final int COUNT = 310;
        
        public static void main (String [] args) 
        { 
                Display display
= new Display(); 
                Shell shell = new
Shell(display); 
                Image image = new
Image (display, SIZE, SIZE); 
                shell.setLayout(new
FillLayout());                
                ToolBar bar = new
ToolBar (shell, SWT.HORIZONTAL);        
          
                for (int i=0; i<COUNT;
i++) 
                {
                    
   ToolItem item = new ToolItem(bar, SWT.NONE);
                    
   item.setImage (image); 
                }
          
                Point point = bar.computeSize(SWT.DEFAULT,
SWT.DEFAULT); 
                bar.setSize(point);
                shell.open();
        
                while (!shell.isDisposed
()) 
                {
                    
   if (!display.readAndDispatch ()) 
                    
   { 
                    
           display.sleep();
                    
   } 
                }
                
                image.dispose();
               
                display.dispose();
        }
