title: Import org.apache.commons.io.FileUtils; not possible in latest apache poi.Instead import org.apache.tools.ant.util.FileUtils; is coming
body: <p>In the latest Apache poi download(poi-3.15-beta2), while taking screenshot, I need to use FileUtils.copyFile. In its previous version, the imported package was <code>import org.apache.commons.io.FileUtils;</code>. In the latest download, this package is not coming, and it is giving error in my existing executable code. Now I tried to remove the previous import and it gave import <code>org.apache.tools.ant.util.FileUtils</code>;</p>
  
  <p>Code:</p>
  
  <pre><code>FileUtils.copyFile(
      scrFile,
      new File(location+"LR_"+strDate+"_scr1.png")
  );
  </code></pre>
  
  <p>Gives the error:</p>
  
  <blockquote>
    <p>Cannot make a static reference to the non-static method
    `copyFile(File, File)` from the type `FileUtils`</p>
  </blockquote>
