Thomas Haselwanter commented on PDFBOX-1019:
--------------------------------------------
Did some investigation at the weekend and found that PDFBox crash in
"org.apache.pdfbox.pdmodel.font.PDSimpleFont" on line 312 - this is the call to
"g2d.drawString....".
But it only seems to crach for fonts "CMR10" and "CMTI10", which leaves the
first page of Petrs' pdf file as shown in the attached image.
Don't know enough about pdf to get further, but maybe this helps.

> The file http://tie.open.ac.uk/256.pdf crashes the JVM during conversion to
> jpeg with the following message :
> Assertion failed: (fnum >= 0 && fnum < t->numSubrs), function BuildSubrs,
> file ../../../src/share/native/sun/font/t2k/t1.c, line 3098.
> Java Result: 134
> The error happens in the method convertToImage():
> PDPage page = (PDPage) pages.get(startPage);
> PDPage page = (PDPage) pages.get(0);
> try {
> image = page.convertToImage();
> } catch (IOException ex) {
> Logger.getLogger(PdfIText.class.getName()).log(Level.SEVERE,
