------------------------------------------------------------------
The change I just made did not revert "your" issue, which dealt with an empty
glyf table.
However compared to 2.0.2 the 2.0.3 version would show nothing in rendering
this file, while the 2.0.2 showed a substitute font.
I'm not yet sure what to, but I just don't want to have the risk of a
NullPointerException.

> The cause is the change in PDFBOX-3395; previously PDFBox would consider the
> font to be bad and replace it. Now we don't do that because the glyf table is
> not always needed.
> I'm throwing an exception for now but a better solution should be found.
> Adobe Reader displays glyphs.
