Tilman Hausherr commented on TIKA-4891:
---------------------------------------
[~tallison] the PDFBox bug has been fixed so it's in the snapshot. From looking
at the PR, my impression is that PDFs with tables won't get much results
because the exception is caught at a higher place (in {{private ElementSpec
buildSpec(StructureIndex.Node node, AttributesImpl attrs)}}). The existing tika
code didn't use the broken method at all.
> Improve handling of PDF/UA structural tags/marked content

> PDF/UA includes structural markup. We hacked out a standalone handler for
> this back in 1.x but haven't touched it in years.
>
> We should modernize our handling of structural tags and eventually consider
> turning that on by default. That decision will be based on evaluation on
> 1000s of PDFs. This is not a default switch to be taken lightly.
