Description Bj 2006-11-29 05:44:46 UTC 
I use POI through Nutch.

Many Word documents cause the following error when being parsed for text extraction:
Can't be handled as Microsoft document.
java.lang.StringIndexOutOfBoundsException: String index out of range: -520

i still see the same problem.

Here is a proposed fix to this issue. 

It simply catches the index out of bounds exception on the substring method
call and returns an empty string in that scenario.

A proposed fix which rewrites the loops

The code gets a List of text runs and a List of text pieces.  The existing code
fails when the start of one text piece is not the same as the end of the
previous piece.  The assumption is made in several places.
My proposed patch rewrites the loop to make the code smaller and simpler.  The
first proposed patch is made obsolete by this patch because the
StringIndexOutOfBoundsException won't happen anymore.

I might be being stupid, but I can't actually figure out what file the most
recent patch applies to...

The patch header refers to WordExtractor.java, but the code doesn't look
anything like org.apache.poi.hwpf.extractor.WordExtractor

One file that trigger a StringIndexOutOfBoundsException with POI 3.2 Final

I also use POI through Nutch and I tried to install POI 3.2 on Nutch 0.9.1.
Although this bug is marked as fixed in POI 3.0, I can reproduce on many documents (I attached one of them) with POI 3.2 FINAL...
