Dennis Adler commented on TIKA-577:
-----------------------------------
Synched to POI 3.8 beta1-20110107 and built it. Ran the same file through and I
still get an IndexOutOfBounds, INdex: 301, Size: 301. Problem is still there
> IndexOutOfBounds Exception looking for Picture in Word 03 doc that has no
> pictures

> Key: TIKA-577
> URL: https://issues.apache.org/jira/browse/TIKA-577
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 0.8
> Environment: Win Pro 7, x64, jdk1.6.0_22, jre 6.0.220.4
> Reporter: Dennis Adler
>
> When cracking a Word 03 document (which, unfortunately, I cannot upload -- it
> has client-confidential data), an index out of bounds exception occurs in the
> POI code used by the WordExtractor. To try to make up for the unavailable doc
> file, I've included the results of a couple of hours stepping through the
> code to find the failure point. The error occurs because point[0] = point[1]
> = 301; upperbound of _paragraphs = 301. This is in the method
> org.apache.poi.hwpf.usermodel.CharacterRun() .
> The method + line numbers are:
> public CharacterRun getCharacterRun(int index)
> line 792: int[] point = findRange(_paragraphs, _parStart,
> Math.max(chpx.getStart(), _start), chpx.getEnd());
> line 794: PAPX papx = _paragraphs.get(point[0]); // <<< This is the
> source of the exception
> STACK at time of exception:
> Range.GetCharacterRun(int) line 794
> PicturesTable.getAllPictures() line 191
> WordExtractor$PicturesSource.<init>(HPWFDocument) line 429
> WordExtractor$PicturesSource.<init>(HPWFDocument, WordExtractor#1) line 419
> WordExtractor.parse(POIFSFileSystem, XHTMLContentHandler) line 75
> OfficeParser.parse(CompositeParser).parse(InputStream, ContentHandler,
> Metadata, ParseContext) line 187
> DefaulttParser(CompositeParser).parse(InputStream, ContentHandler, Metadata,

> ... (my project) ...
> As noted, this occurs in a Word 2003 doc which has no pictures (it is a
> table); 147 character runs (0 - 146) found in first pass. Problem occurs on
> first pass (not sure if there will be others) on this run. Last run in this
> code section from org.apache.poi.hwpf.model.PicturesTable.getAllPictures(),
> lines 186-191:
> public List<Picture> getAllPictures() {
> ArrayList<Picture> pictures = new ArrayList<Picture>();
> Range range = _document.getOverallRange();
> for (int i = 0; i < range.numCharacterRuns(); i++) {
> CharacterRun run = range.getCharacterRun(i);
> Error occurs on getCharacterRun(i) when i = 146, which is the last run in the
> range. If I change point[0] to 300 (in getCharacterRun), the call returns
> nicely to
> WordExtractor$PicturesSource<init>(HPWFDocument) line 429, setting the List
> all to an empty List. Fails again later on subsequent call to
> getAllPictures with same error.
> POTENTIAL FIX: if point[0] > papx.Length then return an EMPTY CharacterRun
> for the paragraph in question.
> Cannot send repro document - contains confidential client data.
