Tim Allison commented on TIKA-2143:
-----------------------------------
I think this may be explained by the following from
[StackOverflow|http://stackoverflow.com/questions/12181872/why-java-treemap-entryset-returns-a-set-of-simpleimmutableentry].
A user was getting exceptions on one server but not the other with the same
code when setting a value in a TreeMap.

Finally found that the problem was caused by this JVM option :
-XX:+AggressiveOpts. It was only present on the server which was raising the
exception. – Jan Aug 30 '12 at 13:59

However, another issue is that if you think you're using Tika 1.13, there's
still an old version of POI somewhere in the class path. Tika 1.9 used POI
3.12, and that version of
[POI|http://svn.apache.org/viewvc/poi/tags/REL_3_12_FINAL/src/scratchpad/src/org/apache/poi/hslf/HSLFSlideShow.java?revision=1678500&view=markup]
lines up with the line numbers in the stacktrace.

> Key: TIKA-2143
> URL: https://issues.apache.org/jira/browse/TIKA-2143
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 1.9, 1.13
> Environment: Windows java application
> Reporter: sbathrutheen
> Priority: Trivial
> Fix For: 1.13
>
>
> We see that TIKA throws a long list of errors when extraction ppt files. We
> tested with standalone tike application (1.13) we cannot reproduce the issue.
> We took a look at POI source code and abserved the class "HSLFSlideShow" we
> could see the below deprecated method defined
> *
> /**
> - * Get the lookup from slide numbers to their offsets inside
> - * _ptrData, used when adding or moving slides.
> - *
> - * @deprecated since POI 3.11, not supported anymore
> - */
> - @Deprecated
> - public Hashtable<Integer,Integer> getSlideOffsetDataLocationsLookup() {
> - throw new
> UnsupportedOperationException("PersistPtrHolder.getSlideOffsetDataLocationsLookup()
> is not supported since 3.12-Beta1");
> - }
> *
> we may think Tika library still calling this deprecated method causing this
> run time Exception
