Bug ID: 60374
Summary: Extracting text from some older Word documents fails
with ArrayIndexOutOfBoundsException due to
unicode/non-unicode mismatch
Product: POI
Version: 3.16-dev
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: HWPF
Assignee: dev@poi.apache.org
Reporter: dominik.stad...@gmx.at
Target Milestone: ---
Created attachment 34447
--> https://bz.apache.org/bugzilla/attachment.cgi?id=34447&action=edit
Sample file
The regression testing at
http://people.apache.org/~centic/poi_regression/reportsAll/ shows the following
for some files.
It seems the text-pieces in the files are stored as non-unicode, but the class
PieceDescriptor sets unicode = true. If I set unicode = false manually there
extracting text works for these documents as well.
public void testException() throws IOException, OpenXML4JException,
XmlException {
final POITextExtractor extractor =
ExtractorFactory.createExtractor(POIDataSamples.getDocumentInstance().openResourceAsStream("cn.orthodox.www_divenbog_APRIL_30-APRIL.DOC"));
// Check it gives text without error
System.out.println(extractor.getText());
extractor.close();
}
