Cannot Instantiate HSSFWorkBook on large excel document

           Summary: Cannot Instantiate HSSFWorkBook on large excel document
           Product: POI
           Version: unspecified
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: HSSF
        AssignedTo: poi-dev@jakarta.apache.org
        ReportedBy: gnangoma@hotmail.com


The HSSFWorkBook construct throws exception when trying to instantiate an excel 
workbook from a large excel document. Specifically, the document has more than 
14,000 rows. 
When reducing the number of rows to ~7,000 no exception is thrown. Must be 
something to do with the number of rows.

Below is the exception:
