Hello!
Open office 4.1.1 says the file made by npoi is corrupted and refuses to open it, even after repair. The file contains nothing but a sheet - no data in it. This happened after I updated to 2.1.1, it worked fine in 2.0.6 (though it corrupted xlsx files).
Corrupted xls attached.
EDIT
Whoops! Sorry, I was actually saving new xssf as xls, my fault.
