Tim Allison commented on TIKA-3094:
-----------------------------------

Thank you [~bob]!

For kicks, I ran the osgi'd Tika against all of our test files and found a few 
more issues.

1) jdom2 is needed by the rss parser
2) java.lang.ClassNotFoundException: javax.xml.bind.JAXBException not found by 
org.apache.tika.bundle [19] ...can't figure out how to fix this
3) We're left with several exceptions caused by adding the wrong type of 
metadata, and we aren't seeing those with regular Tika.  I can't figure out why 
we're getting these in OSGi but not in regular Tika.

On 2), I tried a bunch of variants of the package that should bring that in, 
but had no luck.
On 3), I'll look more closely tomorrow to try to figure out what's going on.

>             Project: Tika
>          Issue Type: Bug
>    Affects Versions: 1.24, 1.24.1
>            Reporter: Abhishek Chauhan
>            Assignee: Bob Paulin
>            Priority: Critical
>         Attachments: Sample PPT.pptx
>
>
> This is regressed from 1.23 version of Apache Tika. Text extraction for .pptx 
> ententions which was earlier working with Apache Tika 1.23 is no longer 
> working in 1.24 version.
> For .ppt extention it is working fine in both 1.23 and 1.24
>  
> As I referred to release notes [https://tika.apache.org/1.24/index.html], you 
> have updated the POI to 4.1.2. That might be the root cause of this problem. 
> POI requires [https://mvnrepository.com/artifact/com.zaxxer/SparseBitSet/1.2] 
> which is not present in bundle I guess.
