Description Tim Riemann 2006-10-20 15:17:04 UTC

We are using POI to index PPT for a P2P search engine. While crawling the web 
we found this document: http://www.na.unep.net/OnePlanetManyPeople/THEMATIC/
Introduction.ppt which cause the following Exception:

Simplest possible testcase showing the ArrayIndexOutOfBoundsError

I use POI through Nutch for parsing Office documents.

Note: No exception is thrown when I do my tests, but a lot of ERROR messages
are logged, indicating that something is wrong:

I use POI through Nutch.

When opening the attachment Nutch logs a series of errors from within POI:

Comment 3 Nick Burch 2007-01-16 07:52:08 UTC

I think this problem has now been fixed, thanks to Yegor's new understanding of
the ordering of TextProps in StyleTextPropAtom

I can open your test powerpoint document without any exceptions, so I'm hoping
this is now closed. If you still get problems, can you re-open with a new
problem file?
