Sample XSSF and Java sample code for reproduce


I tryed to read a Excel 2007 OOXML file with some different cellformats, when I wonder why some dates will be formated wrong.
POI returns for the following formats null as FormatString:
- default value cell (thats the first cell-format-option in excel, called default)
- h:mm:ss AM/PM
- default date cell (thats the first cell-format-option unter the menu date)
- ...
So I can't modify any Formatter because there is no Format returned.
If you run the java sample attached, you will see that a lot of formats returned null.

My sample-xlsx and the java sample code is attached.

Those missing formats are built-in data formats that are implied rather than explicitly saved in the file.
