Hello all,
I'm quite new to pdfbox, but very experienced with java and pdf. I am
getting a null pointer exception closing a PDF file. I believe that the
RandomAccessBuffer.close() method is being called before the FlateFilter is
finished writing to it. Is FlateFilter required? If not, how can I turn
it off to get past this problem?
I added "super(e);" to :
public WrappedException( Exception e )
{
super(e);
wrapped = e;
}
So that the root cause exception would be printed by SLF4J logging. Is
there some reason that was left off?
If I end up debugging the filter issue, what is the mechanism for
submitting a patch? Is there an issue tracker for Pdf Box?
I know there are quite a few questions in this email. Partial responses
welcome?
Thanks,
Eric
Here is the exception I'm getting:
