Incorrect version of POI HSSF

[botatun]

I've got this error when I call my class:

import java.io.*;
import org.apache.poi.hssf.usermodel.*;

public class HssfExample {

  public HssfExample()
  {
     try{
       File f = new File("c:/workbook.xls");
       f.createNewFile();
       InputStream myxls = new FileInputStream(f);

       HSSFWorkbook wb = new HSSFWorkbook(myxls);

     }
     catch(Exception e)
     {
        System.out.println(e.getMessage());
     }

This is the error:

java.lang.UnsupportedClassVersionError: org/apache/poi/hssf/usermodel/HSSFWorkbook (Unsupported major.minor version 49.0)

It is a fresh download. I just loaded the POI-HSSF and want try something to do with it.
How to fix it?
