title: Alfresco exception message format
body: <p>I want to show only my message for alfresco workflow exception. But in alfresco exception message format is that 
   <strong>1. exception.class.name
   2. ErrorLogNumber 
   3. Message</strong></p>
  
  <p>For example,
  <strong><em>org.alfresco.service.cmr.workflow.WorkflowException: 05130007 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX</em></strong></p>
  
  <p>I only want to show 3.Message not 1.exception.class.name and 2.ErrorLogNumber. I can remove ErrorLogNumber from message by adding a custom exception class. But I can't remove 1.exception.class.name from error message.
  Let me know how to implement that.</p>
