Calling getFontMetrics(font) with a very large font causes the window
manager to crash.

When the below program is running getFontMetrics will take longer and longer to process as the font sizes increase. When font size 1000 is used the system
hangs (can't do anything, system is pegged @100%) and eventually the window
manager will crash.

import java.awt.*;

public class FontMetricsTest {

  public static void main(String args[]) {
              
    int fontSize[] = {5,25,50,100,500,1000,10000,Integer.MAX_VALUE};
    Toolkit toolkit = Toolkit.getDefaultToolkit();
        
    for (int i = 0; i < fontSize.length; i++) {
     System.out.println("Font size: " + fontSize[i]);
     Font ft = new Font("TimesRoman", Font.PLAIN, fontSize[i]);
        
        FontMetrics fm = toolkit.getFontMetrics(ft);
System.out.println("Font metrics: " + fm.toString());
    }
  }
}
