[classlib][swing] JComponent.setBounds() should not cause revalidation
----------------------------------------------------------------------

                 Key: HARMONY-1801
                 URL: http://issues.apache.org/jira/browse/HARMONY-1801
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Dmitry A. Durnev
            Priority: Minor


Validation process should not be initiated by component reshaping to avoid too
many re-validations while doing layout (layout usually causes reshape).
Therefore JComponent.setBounds() should not call revalidate. 
Compile & run the following test:

import java.awt.EventQueue;
import java.lang.reflect.InvocationTargetException;

import javax.swing.JButton;
import javax.swing.JFrame;


public class SetBoundsTest {
    
    public static void main(String[] args) throws InterruptedException, InvocationTargetException
{
        final JFrame jf = new JFrame("test");
        final JButton jb = new JButton("1");        
        jf.getContentPane().add(jb);
        jf.setSize(200, 200);
        EventQueue.invokeAndWait(new Runnable(){

            public void run() {
                jf.show();                
            }
            
        });
        EventQueue.invokeAndWait(new Runnable(){

            public void run() {
                jb.setSize(150, 500);                
            }
            
        });
        

        EventQueue.invokeAndWait(new Runnable(){

            public void run() {
                System.out.println(jb.getSize());
                jf.dispose();           
            }
            
        });
        

    }

}

On RI button size set by user(150, 500) is printed. On Harmony some other size (set by layout)
is printed.
