Hi,
@Tilman
Thanks for running all those tests. The results are looking good to me, although
I've to admit that I don't understand every bit of those sheets especially those
about the content ;-)
However, I'm planning to cut the 2.0.23 release next Monday.

Latest run:
http://home.snafu.de/tilman/tmp/reports_pdfbox_2.0.22_vs_2.0.23_6.tar.xz
the two files are gone. (Yeah this does not formally prove that we fixed
it, but lets just believe it does)

Many, many thanks to Tilman for running the regression tests!
The 2 new exceptions are caused by PDFBOX-5127. I'm baffled that we
haven't seen these before, but they do require some rare
circumstances.
The 1 new Tika exception is a zero-byte file exception. This is my
fault because I changed the files between Tilman's runs.
As for XMPBox, Tilman is right that when I tried to use it many years
ago, it did not have the flexibility needed for PDFs in the wild.
See: https://lucene.472066.n3.nabble.com/DISCUSS-options-for-XMP-parsing-td4262520.html
2016 me: "I found that it fails on roughly 40% of XMPs I pulled out of
PDFs from govdocs1/commoncrawl"
Cheers,
Tim

That would be great - maybe together with expected extraction results -
so I can start with proper unit tests. If you could add to
https://issues.apache.org/jira/browse/PDFBOX-5128
that would be great.

would it make sense to add that support? If yes could we get samles of
various schema to support that development? Could look into that if we

The three new exceptions weren't in earlier reports.
IIRC the reason Tika uses Jempbox is because Xmpbox fails when there is
a non standard schema.

As far as I remember the jempbox issue isn't new, Tim mentioned it some time
ago. Just out of curiosity does it make sense to use an old lib to extract
metadata? Is there anything missing in xmpbox but available in jempbox?

The content differences part is now the smallest ever, likely due to my
change in tika-eval (TIKA-3314) and restoring a PDFBox code segment I
accidentally deleted (PDFBOX-5115).
There are three new exceptions. Two are in jempbox and one is in tika
itself so I suspect PDFBox isn't to blame. I'll look at it too if I have
the time.

I think we're good (despite the differences, most of which are because
of the soft hyphen), but I'm now experimenting with a modified version
of tika-eval to see what happens.

There's not much changed. No new exceptions. Re content, the changes
that seem important are all related to "soft hyphen".
https://issues.apache.org/jira/browse/PDFBOX-5115
I am currently fixing this, and then I'll run the tests again. The text
extraction differences will likely stay. It's possible that a change in
tika-eval is needed too.
