Summary: Poi will corrupt xls file when there is a 'Chart
sheet' in the Excel file, Excel 2010
Product: POI

original file and corrupted file
If the xls file has a 'Chart sheet', poi method Workbook.write(OutputStream)
will corrupt the file. Excel 2007 and earlier does not show the corruption, but
Excel 2010 will detect the corruption and show it.
What we have done here is straightforward. We use HSSFWork's constructor,
HSSFWorkbook(FileInputStream) to read a xls file with Chart sheet from disk,
and directly write it back using method Workbook.write(OutputStream). The file
is corrupted afterwards.
I attached a zip file here including: 1. the original xls file, 2. the
corrupted file, and 3. the screen shot from Excel 2010 when opening the
corrupted file.
