Estoy tratando de insertar una tabla usando apache-poi en formato .docx usando open office ... Pero el archivo se bloquea cada vez que lo abro

      XWPFDocument document= new XWPFDocument();
      FileOutputStream out = new FileOutputStream(new File("C://create_table.docx"));

      //create table
      XWPFTable table = document.createTable();

      //create first row
      XWPFTableRow tableRowOne = table.getRow(0);
      tableRowOne.getCell(0).setText("col one, row one");
      tableRowOne.addNewTableCell().setText("col two, row one");
      tableRowOne.addNewTableCell().setText("col three, row one");

      //create second row
      XWPFTableRow tableRowTwo = table.createRow();
      tableRowTwo.getCell(0).setText("col one, row two");
      tableRowTwo.getCell(1).setText("col two, row two");
      tableRowTwo.getCell(2).setText("col three, row two");

      //create third row
      XWPFTableRow tableRowThree = table.createRow();
      tableRowThree.getCell(0).setText("col one, row three");
      tableRowThree.getCell(1).setText("col two, row three");
      tableRowThree.getCell(2).setText("col three, row three");

      document.write(out);
      out.close();
      System.out.println("create_table.docx written successully");
   }
