PM86348: THE EXCEPTION MESSAGE WAS NULL WHEN USING UNKNOWN TAGS IN SERVER.XML

APAR status

• Closed as program error.

Error description

• When adding an unknown tag in server.xml for the first time
  such as <aa></aa>, there is a warning:
  
  Liberty Profile console will report:
  
  [WARNING ] CWWKE0405W: An exception occurred while notifying a
  monitor of the following file creations, modifications, and
  deletions: [],
  [C:\liberty\20121122\usr\servers\defaultServer\server.xml],
  []. The monitor class is class
  com.ibm.ws.config.internal.xml.XMLBundleProcessor$ConfigFileMoni
  tor. The exception message was: null
  
  
  Then if the server.xml is changed and saved (keep this
  <aa></aa>  in server.xml), it won't report this message
  anymore. (even if I restart the server)
  
  [AUDIT  ? ? ] CWWKG0016I: Starting server configuration update.
  [AUDIT  ? ? ] CWWKG0018I: The server configuration was not
  updated. No functional changes were detected.
  
  The console message doesn't help much. ? ? You really don't
  know what's wrong when reporting "The exception message was:
  null ".

  * PROBLEM DESCRIPTION: Confusing warning message when          *
  *                      updating the server configuration       *

  ****************************************************************
  An internal exception may occur during configuration update
  processing when an unknown element is added to the server
  configuration. The internal exception is reported as a
  warning, but does not provide adequate information about what
  went wrong or how you should resolve the problem.
  

Problem conclusion

• The code was fixed so that the internal exception will never
  occur.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5. Please refer to the Recommended Updates page
