 /**
 19  
  * <code>AbstractEventAwareTransformer</code> is a transformer that has a reference
 20  
  * to the current message. This message can be used obtains properties associated
 21  
  * with the current message useful to the transform. Note that when part of a
 22  
  * transform chain, the Message payload reflects the pre-transform message state,
 23  
  * unless there is no current event for this thread, then the message will be a new
 24  
  * MuleMessage with the src as its payload. Transformers should always work on the
 25  
  * src object not the message payload.
