      Description

      I have a frame which contains scrollpane having ScrollPane.SCROLLBARS_AS_NEEDED policy set to it. A button is added to the scrollpane. While resizing the frame (make the frame to be smaller) scrollbars of the scrollpane can be seen , but just for a second ( flashes ).

      import java.awt.ScrollPane;
      import java.awt.Frame;
      import java.awt.Button;

      public class TestScrollPaneResize {
              private Frame frame=null;
              private ScrollPane sp=null;
              private Button b=null;

              TestScrollPaneResize(){
                      frame = new Frame("Test ScrollPane resize test");
                      sp = new ScrollPane( ScrollPane.SCROLLBARS_AS_NEEDED );
                      sp.add(new Button("Press Me..!"));
                      frame.add("Center",sp);
                      frame.setSize(300,300);
                      frame.setVisible(true);
              }
              public static void main(String []args){
                      new TestScrollPaneResize();
              }
      }

      Step to Reproduce:
      -------------------
      1) Run the attached program.
      2) Resize the frame(to make it smaller). Move the mouse to the left bottom corner of the frame, Press the mouse left button & move towards inside. Observe carefully, while releasing the mouse ,you can see the scrollbars just for a second(flashes). If you see the same then the bug is reproduced.
      This happens only in XToolkit(i used mustang b101), this can't be seen in Motif toolkit ( i used 1.5.0/fcs/b64). Hence this is a regression.
