> It seems when writing a PDF that has an invalid embedded font to an image
> there is a crash in the native function sun.font.FileFont.getGlyphImage(JI).
> It can be reproduced using the PDFToImage program on a pdf with an invalid
> embedded font.
> Turing on -Dsun.java2d.debugfonts=true on a bad pdf will show some like the
> follow for the bad font
