  Font f = Font.createFont(Font.TYPE1_FONT, new File("hrger.pfa"));
  FontMetrics fm = Toolkit.getDefaultToolkit().getFontMetrics(f);
  fm.getWidths(); //Index out of bounds is thrown here.

Test source code and font file are attached to this CR.

This can be reproduced on openjdk 6 "build 1.6.0-ea-b10" on at least
solaris x86 and linux.
 

on jdk 7 the test code above runs successfully on both solaris and linux.
