Subject [jira] [Commented] (TIKA-1737) PDFBox 1.8.10 is still a basket case
Date Tue, 22 Sep 2015 21:04:04 GMT

Alan Burlison commented on TIKA-1737:
-------------------------------------

bq. Re the ArrayIndexOutOfBoundsException - are you using multithreading? I wonder if it is
possibly related to PDFBOX-2824. That was fixed in the 2.0 version only.

Yes, the app is MT and it does indeed look very much like PDFBOX-2824

bq. Re the NPE in PDFStreamEngine.java:355 - this is possibly solved in 1.8.11.

OK, thanks - PDFBOX-2987, correct?

> In TIKA-1471 I reported OOM errors when parsing PDF files. According to that bug the
issues were fixed in 1.7. I've just updated to Tika 1.10 and rather than PDFBox being better
it's actually far, far worse. With the same corpus, Tika 1.5 (PDFBox 1.8.6) has 13 exceptions
thrown by PDFBox, Tika 1.10 (PDFBox 1.8.10) has *453* exceptions thrown by PDFBox. Not only
that, but as far as I can tell, the memory leaks are even worse in 1.8.10 as well.
> I've had to resort to destroying the Tika instances and starting over each time there's
an error indexing a PDF file. It's so bad I'm going to switch to running pdftotext (part of
Xpdf) as an external process. Note that many of the errors in PDFBox are clearly caused by
programming errors, e.g. ArrayIndexOutOfBoundsException, ClassCastException, NullPointerException
and EOFException.
> I strongly recommend that Tika either reverts back to PDFBox 1.8.6 or finds a replacement
for PDFBox as 1.8.10 just isn't fit for purpose.
