Confluence ignores the system property officeconnector.textextract.word.docxmaxsize

Summary

In the current System Properties documentation there is a setting officeconnector.textextract.word.docxmaxsize, and this is ignored by Confluence when set in setenv.sh.

Environment

• Confluence 5.8.x or Confluence 5.9.x

Steps to Reproduce

1. Add to setenv.sh
   setenv.sh

   CATALINA_OPTS="-Dofficeconnector.textextract.word.docxmaxsize=1000 ${CATALINA_OPTS}"
   

2. Insert the attached file lorum.docx to a page.
3. Check the logs, the error
   atlassian-confluence.log

   com.atlassian.bonnie.search.extractor.ExtractorException: Error reading content of Word XML document: Document too big for text extraction, bailing out
   

   does not appear.

Expected Results

The error

com.atlassian.bonnie.search.extractor.ExtractorException: Error reading content of Word XML document: Document too big for text extraction, bailing out

should appear as the file size is now 1K.

Actual Results

The file is indexed correctly.

Notes

For the attached file you will need to increase your Java Heap Space in setenv.sh to something like -Xmx8192m.

The value officeconnector.textextract.word.docxmaxsize is referenced in com.atlassian.confluence.extra.officeconnector.index.word#WordXMLTextExtractor.java as

private static final long MAX_XML_SIZE = Long.getLong("officeconnector.textextract.word.docxmaxsize", 1024 * 1024 * 16); // Maximum, 16Mb of XML text, more than enough for most files
...
if (finalSize > MAX_XML_SIZE) {
                        throw new ExtractorException("Document too big for text extraction, bailing out");
                    }
