Joshua Davies commented on JIBX-153:
------------------------------------

I was able to pare the binding that reproduces the error down a little bit, so 
the stack trace isn't quite so large:

<binding direction="both">
  <mapping name="RoomRate" class="RoomRateType" >
    <structure name="Features" usage="optional" test-method="hasRoomPromotions" 
>
      <collection field="roomPromotions" usage="optional">
        <structure name="Feature" usage="optional">
          <structure name="Description" usage="optional"
                     type="ParagraphType">
            <value style="element" name="Text" field="text" usage="optional"/>
          </structure>
        </structure>
      </collection>
    </structure>
  </mapping>
</binding>

The class files in the attachment are the same.
