2351597 - dswsbobje webservices do not work after patching to 4.2 SP2 patch 3

After applying BI 4.2 SP02 Patch3 on a BI 4.2 SP02 standalone server [which itself was upgraded from early BI 4.1 versions], the following symptoms were seen -

• The dswsbobje webservices provider does not work as expected when used with BI platform consumers (clients). 
• The issue impacts all dashboards using QaaWS, QaaWS Client Login, Design Studio Client Login.
• Error Message Displayed in Browser (as shown below):
  Cannot Access External Data
  soapenv:Server: java.lang.NoSuchMethodError: com.businessobjects.dsws.impl.DSWSExceptionDocumentImpl.generatedSetterHelperImpl(Lorg/apache/xmlbeans/XmlObject;Ljavax/xml/namespace/QName;IS)Lorg/apache/xmlbeans/XmlObject;
  
  
  
• The issue also affects Design Studio Client login which does not work because the authentication is blank as shown below
  
  Error: could not initiate connection. Check the Web Service URL
  
  
• The QAAWS client login also gives an error with similar behavior ie. authentication is blank
  
  Error: Web Services URL is not correct.
  
  
  
  
• The dswsbobje url itself works fine on a supported Web Browser.

• SAP BusinessObjects BI Platform 4.2 SP02 Patch 3 [ this may also occur with other patches ]
  All supported operating systems
