Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of the IBM MQ Console who are attempting to create and
  delete 'create authority records'.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  There were several problems in the way in which the IBM MQ
  Console 'create authority records' function was being managed
  within the IBM MQ Console, which resulted in the IBM MQ Console
  being unable to delete 'create authority records'.
  
  When the delete function was attempted, a NullPointerException
  was seen in the Web Console, as well as an error message in the
  application server's messages.log file.  In addition, an ffdc
  was also generated, with contents of the form:
  
  ------Start of DE processing------ = [01/02/19 16:38:43:703 GMT]
  Exception = java.lang.NullPointerException
  Source =
  com.ibm.ws.webcontainer.filter.WebAppFilterManager.invokeFilters
  probeid = 1105
  Stack Dump = java.lang.NullPointerException

          ... ... ...
  
  
  Note that this problem did not concern the management of
  'authority records' within the IBM MQ Console - only the 'create
  authority records' were affected.
  

Problem conclusion

• The IBM MQ Console application has been reworked in the area of
  the management of 'create authority records', so that they now
  behave in the intended manner.
