title: How can restart a spring batch from specific point if ends abruptly
body: <p>After read a lot about restarting in Spring Batch, i've learnt that:</p>
  <ul>
  <li>SB can restart a step from the beginning where a job has failed.
  Example: Job1 -&gt; step1, step2, step3 (FAIL) -&gt; then you can restart from step3</li>
  </ul>
  <p>I would like another behaviour, but I didnt find any solution that fits me.</p>
  <p>I have a job with a single step.
  This step read a text file (can have a lot of lines).
  I want to cover our system in case of a non-expected ending (for example, our server shutdown abruptly)
  In this case if we have read X lines, i want to recover the job from X+1 lines to the end.</p>
  <p>¿Is it this possible to achieve?</p>
  <p>Thanks in advance.</p>
