java.awt.font.GlyphVector.getGlyphPosition(int glyphIndex) does not throw any exception when java.lang.Integer.MIN_VALUE is passed to the int argument glyphIndex. But as per the spec the method is supposed to throw IndexOutOfBoundsException.

Sample Test
-----------
import java.awt.font.GlyphVector;
import java.awt.geom.Point2D;
import java.awt.Font;
import java.awt.font.FontRenderContext;
import java.awt.geom.AffineTransform;

public class Test{

public static void main(String[] arg){

  Font font = new Font("Courier",Font.ITALIC,20);
  FontRenderContext fontRC=new FontRenderContext(
new AffineTransform(),true,true);
  GlyphVector gv = font.createGlyphVector(fontRC,"Hello") ;
  Point2D gj=gv.getGlyphPosition(Integer.MIN_VALUE);
  System.out.println(gj.getX()+","+gj.getY());
 }
}
