Run the follwing in SWT and RAP:
---
    public int createUI() {
      Display display = new Display();
      Shell shell = new Shell( display, SWT.TITLE | SWT.CLOSE );
      shell.setLayout( new GridLayout( 1, false ) );
      Button button = new Button( shell, SWT.PUSH );
      button.setText( "push" );
      final ToolTip tooltip = new ToolTip( shell, SWT.NONE );
      tooltip.setMessage( "foo" );
      tooltip.setText( "bar" );
      tooltip.setLocation( 200, 200 );
      button.addSelectionListener( new SelectionAdapter() {
        public void widgetSelected(SelectionEvent e) {
          tooltip.setVisible( true );
        }
      } );
      shell.layout();
      shell.open();
      while (!shell.isDisposed()) {
          if (!display.readAndDispatch()) {
              display.sleep();
          }
      }
      return 0;
    }

SWT: ToolTip is not visible at first. Its shown when pushing the button, stays for a few seconds, then fades. Pushing the button again and the tooltip appears again.

RAP: ToolTip can be shortly seen fading out when the application starts. Its shown when pushing the button, stays for a few seconds, then fades, just like in SWT. Pushing the button again does nothing.

Not sure why pushing the button again doesnt work, might be a server-side issue. The animation at application start can probably be prevented by setting the default value of the client-property "visibility" to false. (An educated guess.)
