body: <p>After I update android annotation library version to 4.0.0 from 3.0+, I cannot build the application. My project can build successfully with android annotation 3.0+ but cannot with 4.0.0.
  When I check the android annotation log file, it show the following errors repeatly(8 times).</p>
  
  <pre><code>11:57:33.458 [Daemon worker Thread 5] ERROR o.a.i.p.ModelValidator:74 - Unrecognized type. Please let your attribute be primitive or implement Serializable or Parcelable or an annotated Parceler bean.
  11:57:33.459 [Daemon worker Thread 5] WARN  o.a.i.p.ModelValidator:85 - Element selectedContacts invalidated by ExtraHandler
  </code></pre>
  
  <p>All generated files from android annotation cannot generate because of this error, so, I could not manage to find the source of error. 
  Could you please suggest me about what can be the source of this error? </p>
  
  <p>Thanks.</p>
