The error message for PUT failure with status code 412 is not very clear when using ETM API and RQMUrlUtility

The error message for PUT failure with status code 412 is  very lengthy, but not very clear when using ETM API and RQMUrlUtility.

Steps to Reproduce:
1. Using a REST client or RQMUrlUtility, do a GET request to get the XML of a Test Case result
https://RQMserver:9443/qm/service/com.ibm.rqm.integration.service.IIntegrationService/resources/_CcnecUbNEfC1q8iEhMAiRg/executionresult/urn:com.ibm.rqm:executionresult:123
2. Open the Test Case result in RQM UI and make a small change like updating a category value and save.
3. Go back to the REST client or RQMUrlUtility and do a PUT using the xml from step 1. 
It fails with status code 412 which is expected, but the error message has too much extra fluff that is not very useful. Also, it would help the end user if the “message” part was more descriptive about the real cause of failure, similar to what is reported in web UI for such failures , e.g. “You have an older state of this item”
