---------------------------------------------------------------
I opened the CMR10 font in fontforge. It is loaded without problem, contains
most characters from ASCII range. Running 'validate' option shows:
- Missing Points at Extrema
- Private Dictionary
-- Elements in BlueValues/OtherBlues array are disordered
-- Elements in BlueValues/OtherBlues array are too close (Change BlueFuzz)
-- Bad BlueScale entry
So I'm not sure about the correctness of the font.

> Key: PDFBOX-1019
> URL: https://issues.apache.org/jira/browse/PDFBOX-1019
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 1.5.0
> Environment: Linux Ubuntu, Mac OSX
> Reporter: Petr Knoth
> Assignee: Andreas Lehmkühler
> Attachments: CMR10.font, CMR17.font, thumb.png

> 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,
> null, ex);
> }
> The problem occurs not for all files, but is critical as it stops my
> webserver (Tomcat) that needs to be then restarted.
