------------------------------------------------------

                 Key: HARMONY-4617

Here is simple reproducer:
import java.awt.*; 
import java.awt.geom.*; 
import java.awt.image.BufferedImage; 
import java.awt.event.*; 
import java.lang.Math;
import javax.swing.JFrame; 

public class Test { 
    public static void main(String[] args) { 
        final Font font = new Font("Dialog",Font.PLAIN, 12); 

            JFrame f = new JFrame("Test"){ 
                public void paint(Graphics g){ 
                    Graphics2D g2d = (Graphics2D)g; 
                    BufferedImage bi = new BufferedImage(100,100,BufferedImage.TYPE_INT_ARGB);

                    Graphics2D g2 = bi.createGraphics(); 
                    g2.setFont(font); 
                    g2.setColor(Color.red); 
                    g2.drawString("Test", 50, 80); 
                    AffineTransform at = new AffineTransform();
                    at.setToRotation(Math.PI/2, 100, 100);
                    g2d.setTransform(at); 
                    g2d.drawImage(bi,0,0,null); 
                } 
            }; 
             
            f.setBounds(0, 0, 300, 300); 
            f.setVisible(true); 
            f.addWindowListener(new WindowAdapter() { 
                public void windowClosing(WindowEvent ev) { 
                    System.exit(0); 
                } 
            }); 
        } 
    } 

Investigation of this issue shows - XSurface can't create Raster, because it receive negative
ROI coordinates.
