[jira] [Comment Edited] (PDFBOX-1019) PDF conversion to image crashes the JVM

["Timo Boehme (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-1019?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13791268#comment-13791268 ]

---------------------------------------------------------------

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.

> 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.
