• Closed as program error.

Error description

• Invalid Tag exception occurs only when using the "version=5"
  format since the stat names are created as an Element and not
  added as an Attribute. This exception happens when the XML
  Parser encounters a character that cannot be parsed.
  
  Customer Recreation Secnario:
  
  1. Starting Deployment Manager
  2. Starting Nodeagent
  3. Starting AppServer "PerfServlet_l0190se080_1"
  4. Sending request
  http://l0190se080.prod7330.dakitest.de/wasPerfTool/servlet/perfs
  ervlet?port=8879&version=5
   --> Reponse is a correct xml (see
  "Perfservlet_with_version5_successful_execution.xml")
  5. Starting AppServer "WCMS_Intranet_0_l0190se080_1"
  6. Sending again same request
  http://l0190se080.prod7330.dakitest.de/wasPerfTool/servlet/perfs
  ervlet?port=8879&version=5
