Cannot open output in Libreoffice

[akbertram]

I'm unable to open output in LibreOffice Calc from a simple test case from fastexcel-writer 0.10.7:

public class FastExcelTest {

    @Test
    public void simpleWorkbook() throws IOException {
        OutputStream os = new FileOutputStream("/tmp/test2.xlsx");
        Workbook wb = new Workbook(os, "MyApplication", "1.0");
        Worksheet ws = wb.newWorksheet("Sheet 1");
        ws.value(0, 0, "This is a string in A1");
        ws.finish();
        wb.finish();
        os.close();
    }
}

If I try to open it in LibreOffice Calc, I get the message:

The file 'test2.xlsx' is corrupt and therefore cannot be opened. LibreOffice can try to repair the file.

If I choose "Yes", LibreOffice is unsuccessfully with the repair.

Am I missing something?

The version of LibreOffice is:

Version: 5.1.6.2
Build ID: 1:5.1.6~rc2-0ubuntu1~xenial7

Nevermind, was not actually using fastexcel-writer 0.10.7! It works with the latest version.
