The com.sun.java.swing.JScrollBar.setValues(int,int,int,int) incompatible with
specification. It does not set minimum < maximum and extent >= 1.

"
 public void setValues(int newValue,int newExtent,int newMinimum,int newMaximum)
      Ensures that the model is always in a consistent state by enforcing
      the following constraints.

         minimum < maximum
         minimum <= value
         extent >= 1
         value <= maximum - extent
      If neccessary we change newValue and newExtent, newExtent is forced to be
       greater than 0.

-------------------Example-----------------------------------
import com.sun.java.swing.*;
public class TestSetValues {

  public static void main(String[] args) {
      JScrollBar c = new JScrollBar();
      c.setValues(0,0,0,0);
      
      if (!( c.getMinimum()<c.getMaximum() && // Check the state
          c.getMinimum()<=c.getValue() &&
          c.getModel().getExtent()>=1 &&
          c.getValue()<=(c.getMaximum()-c.getModel().getExtent() ))) {
       
       System.out.println("Wrong values:"+c);
       return;
      }
       System.out.println("OKAY");
       return;
  }
}
-------------------Output------------------------------------
Wrong values:com.sun.java.swing.JScrollBar[vertical, value=0, adj=false, extent=0, min=0, max=0, unit=1, block=0]
