Description amseager 2017-10-13 09:36:47 UTC
Tried to open docx file in that way:

File wordFile = new File(wordFilePath);
OPCPackage wordPackage = OPCPackage.open(wordFile, PackageAccess.READ_WRITE);
XWPFDocument wordDocument = new XWPFDocument(wordPackage);

Then I caught this exception:

Exception in thread "main" org.apache.poi.openxml4j.exceptions.OpenXML4JRuntimeException: Rule M2.4 exception : this error should NEVER happen! If you can provide the triggering file, then please raise a bug at https://bz.apache.org/bugzilla/enter_bug.cgi?product=POI and attach the file that triggers it, thanks!

File which triggered an exception

Couldn't send it directly (Bugzilla rased an error), so I zipped it

The first zip contains an document with zero bytes length. The second does not reproduce the problem for me with the latest version of POI.

Therefore I am closing this as INVALID for now, if this is still a problem for you please re-run the example with the latest version of Apache POI and then reopen and attach both the triggering document and the full self-sufficient code for reproducing the problem here.
