Build Identifier: 

1 I wrote a demo to put a swt into canvas. In windows ,it is OK and could show two buttons.
import org.eclipse.swt.*; 
import org.eclipse.swt.awt.*; 
import org.eclipse.swt.layout.*; 
import org.eclipse.swt.widgets.*; 

public class SWTInAWT { 
public static void main(String[] args) { 
        java.awt.Frame frame = new java.awt.Frame("AWT Frame"); 
        java.awt.Button button = new java.awt.Button("AWT Button"); 
        frame.add(button, java.awt.BorderLayout.NORTH); 
        java.awt.Canvas canvas = new java.awt.Canvas(); 
        frame.add(canvas, java.awt.BorderLayout.CENTER); 

        frame.addNotify(); 
        
        Display display = new Display(); 
        Shell shell = SWT_AWT.new_Shell(display, canvas); 
        shell.setLayout(new FillLayout()); 
        Button swtButton = new Button(shell, SWT.PUSH); 
        swtButton.setText("SWT Button"); 
        frame.setBounds(20, 20, 300, 300); 
        
        shell.layout(); 
        frame.setVisible(true); 
        
        while (!shell.isDisposed()) { 
                if (!display.readAndDispatch()) display.sleep(); 
        } 
        display.dispose();
} 
} 

2 when I run it in linux Redhat 5 EL, it will throwException.

3 I put the *.so in swt-3.6-gtk-linux-x86.jar into this directory. It also can not run. 

Reproducible: Always
