JasperLibrary 6.16 can NOT create correct XLSX

Hello

I have problem to open export in XLSX format

When i try open xlsx by Office 365 i get warning about incorrect content of XLSX.

1. When i remove directory \xl\drawings from zip of xlsx it can be open with Office 2016 but not Office 365

2. My report's have NO any drawing

3. When i try open by Office 365 xlsx (\xl\drawings NOT Deleted ) Excel CAN recover xlsx but it takes long long time on a huge report.

In my zip i put jrxml, code for export, result xlsx
