            Bug ID: 55519
           Summary: OOXML text extractors should open package as read-only
           Product: POI
           Version: 3.10-dev
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: POI Overall
          Assignee: dev@poi.apache.org
          Reporter: qforce@users.sourceforge.net

Hi,

In the method ExtractorFactory.createExtractor(File), an OPCPackage is created
with OPCPackage.open(f.toString()).

This opens the package with PackageAccess.READ_WRITE. IMHO, a text extractor
should open with PackageAccess.READ instead. Not doing so may cause POI to
modify the file when the package's close method is called for some reason, a
behavior a client would not expect from a text extractor.

Also, in my case, this issue caused my program to get stuck in an infinite
loop, as the program was constantly reindexing files which it thought were
modified.

Best regards
