title: @ManyToOne and @BatchSize
body: <p>I found in some old code strange thing (at least for me).</p>
  
  <p>The field which is annotated <code>@ManyToOne</code> is also annotated with <code>@BatchSize</code>. </p>
  
  <p>I always thought that <code>@BatchSize</code> annotation only affects when annotated at class level or on a collection (<code>@OneToMany</code>) and affects <strong>pre-fetching</strong> when iterating.</p>
  
  <p>But maybe I am wrong and annotating <code>@ManyToOne</code> with <code>@BatchSize</code> affects something. I can't find the answer in the documentation.</p>
  
  <p>Does annotating <code>@ManyToOne</code> with <code>@BatchSize</code> have sense?</p>
