            Bug ID: 55605
           Summary: NullPointerException during iteration over CTSheets
           Product: POI
           Version: 3.8
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: XSSF

Proposed solution to this issue

The problem ocurrs during iteration over CTSheets, in class SheetIterator with
a excel file with macros.

The null pointer exception is thrown when next() function is called.

In next() function:

It seems  that 

  ctSheet.getId(); 

returns a null or blank value so when  

  sheetMap.get(sheetId);

is called, it returns null value which causes the Null Pointer Exception in
this line:

  return sheetPkg.getInputStream();



Regards
Diego.
