Description

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.
