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?
> PDFBox 1.8.10 is still a basket case

> Key: TIKA-1737
> URL: https://issues.apache.org/jira/browse/TIKA-1737
> Project: Tika
> Issue Type: Bug
> Components: general
> Affects Versions: 1.10
> Environment: Linux, Solaris
> Reporter: Alan Burlison
> Attachments: pdfbox.txt
>
>
> 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.
