I have an very old .xls file,when I use code blow to change its content:
```
String filePath = "D:\\BRD2002.xls";
try {
Workbook workbook = new HSSFWorkbook(new
FileInputStream(filePath));
Sheet sheet = workbook.getSheetAt(0);
int rowIndex = 2;
sheet.shiftRows(rowIndex, sheet.getLastRowNum(), 1);
Row row = sheet.createRow(rowIndex);
row.createCell(0).setCellValue("switch");
FileOutputStream outputStream = new FileOutputStream(filePath);
workbook.write(outputStream);
outputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
```
An Exception came out At row：'workbook.write(outputStream);'
Exception details:
```
java.lang.ClassCastException: class org.apache.poi.hssf.record.DSFRecord cannot
be cast to class org.apache.poi.hssf.record.TabIdRecord

```
When I commented out the line of code that contains "sheet.shiftRows" and
executed it again, there were no exceptions anymore.
