Opening .xlsx created in MsExcel 07 with apache poi causes POIXMLException

Question

i am using XSSFWorkbook from Apache Poi "3.10-FINAL" in order to read .xlsx files.

Working on .xslx produced by Ms Office '03 and '13 everything works fine and i can open the .xlsx like this:

InputStream is = new ByteArrayInputStream(xlsxInByteArray);
XSSFWorkbook wb = new XSSFWorkbook(is);

With some file produced in MS Office '07 version : 12.0.6683 SP3 MSO (12.0.6683.5000) the constructor of XSSFWorkbook raises the exception :

org.apache.poi.POIXMLException: org.apache.poi.openxml4j.exceptions.InvalidFormatException:
Package should contain a content type part

Also tried another way using WorkbookFactory

InputStream is = new ByteArrayInputStream(xlsxInByteArray);
Workbook wb = WorkbookFactory.create(is);

to open this file and i get another exception :

Your InputStream was neither an OLE2 stream, nor an OOXML stream 

Any clues?

I can provide you some information about the file concerned : This is the Apache Tika's analysis =
