    [ https://issues.apache.org/jira/browse/PDFBOX-1019?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13044512#comment-13044512 ] 

Craig Stires commented on PDFBOX-1019:
--------------------------------------

Had posted a possible related issue to the mailing list, but haven't seen if this helped resolve this issue

Try the patch from
https://issues.apache.org/jira/browse/PDFBOX-988

this may be the same issue of a font not having enough glyphs, and making the g2d.drawString crash or hang

see if that makes a difference for you, or not

> 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.
