      Description

      There is a problem generating the xls file for the "Grade Report" when there are two or more assignments with more than 100 submissions in total.

      The problem is that the "SXSSFWorkbook" class has a default limit of 100 rows to maintain in memory. When it has 101 or more elements, it starts to flush the first elements, which are no longer accessible.
