Implementation of the JTable.getScrollableBlockIncrement() has been incompatibly
changed in JDK-1.2.2-H.

(See JavaDoc comments)
public int getScrollableBlockIncrement(Rectangle visibleRect,
                                       int orientation,
                                       int direction)

  Returns The visibleRect.height or visibleRect.width, depending on the table's
  orientation.

This method has complied with the specification until JDK-1.2.2-H. Starting with
JDK-1.2.2-H it does not return visibleRect.height when orientation is
SwingConstants.VERTICAL.

Here is the test example:

------------------ Test.java -----------------
import java.awt.*;
import javax.swing.*;

class Test {

    public static void main(String[] argv) {

       JTable c = new JTable();
       Rectangle r = new Rectangle(10,30);
       System.out.println(" VERTICAL ScrollableBlockIncrement "+
                c.getScrollableBlockIncrement(r,SwingConstants.VERTICAL,0));
       System.out.println(" Should be "+r.height);

       System.exit(0);
    }
}
