title: How to use blob with ebean & play 2?
body: <p>This is the entity contains blob type:</p>
  
  <pre><code>@Entity
  @Table(name="image_info")
  public class ImageInfo extends Model {
  
      .......
  
      @Constraints.Required
      private Blob image;
  
      .......
  }
  </code></pre>
  
  <p>$ play -DapplyEvolutions.default=true run</p>
  
  <p>I got errors like the following:</p>
  
  <pre><code>[warn] c.j.b.ConnectionPartition - BoneCP detected an unclosed connection and will now attempt to close it for you. You should be closing this connection in your application - enable connectionWatch for additional debugging assistance.
  [error] c.a.e.s.t.r.ImmutableMetaFactory - Was unable to use reflection to find a constructor and appropriate getters forimmutable type interface java.sql.Blob.  The errors while looking for the getter methods follow:

  <p>How could I make the change so blob type can be recognized?</p>
