A DESCRIPTION OF THE PROBLEM :
Calling FontMetrics.stringWidth(string) after setting a very large font size (e.g. 32000) causes the Java VM to crash with a SIGSEGV. Interestingly, larger numbers (e.g. 50000) do not cause the crash.

THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: Yes

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Yes

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the attached program

EXPECTED VERSUS ACTUAL BEHAVIOR :
  Program should print out a number (-53695 on 1.5.0_11).

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Attached seperatly

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import java.awt.Font;
import java.awt.FontMetrics;
import java.awt.Graphics2D;

import javax.swing.JFrame;


public class TestBug extends JFrame {

public TestBug() {
}
public void test() {

Font f=new Font("culfont",Font.PLAIN,30000);

Graphics2D g=(Graphics2D) this.getGraphics();

g.setFont(f);
FontMetrics fm=g.getFontMetrics();
String string="LAKE";

int length=fm.stringWidth(string);
System.out.println("Size: "+length);




}

public static void main(String[] args) {
TestBug tb=new TestBug();
tb.setVisible(true);
tb.test();

}

}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Make sure the application doesn't use excessively large font size. This actually demonstrated a bug in my application, but the VM should handle it gracefully.
