Unable export more than 256 columns into *.xlsx format.
Steps to reproduce:
- Create a POJO with 256+ properties;
- Save template 'object_collection_template.xls' as 'Excel Workbook (*.xlsx)' format
- Add more than 256 columns and change the comments to accommodate this change; 4.Modify ObjectCollectionByColumnsDemo to point to the new file (also, be aware that getResourceAsStream will only work for the full path. E.g. "/org/jxls/demo/guide/object_collection_template.xlsx");
- Modify 'generateSampleEmployeeData' method to populate the POJO with all the data;
- Run test.
All the columns in the exported file are filled.
The data is filled up to column IV. In addition, one can see in the logs several java.lang.ArrayIndexOutOfBoundsException errors being thrown.
