Adam Nichols commented on PDFBOX-1019:
--------------------------------------
I was able to duplicate this issue using the Oracle JVM 1.6.0_23 on Linux
(32-bit Ubuntu). Added 256.pdf to the resources directory and a test case to
PDSimpleFontTest so others can easily test this issue. I'm including the full
log output from the test case so we can try to determine whether this is a JVM
bug or an issue with PDFBox.

> 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
> Priority: Blocker
> Attachments: 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.
