Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of Business Process Manager v8.5 who use promoted
  properties in a mediation flow
  
  ****************************************************************
  PROBLEM SUMMARY:
  If a promoted property is created for a mediation primitive
  but not given a value this will result in a NullPointerException
  in the code when this unset value is accessed
  

Problem conclusion

• The code was changed such that a NullPointerException will no
  longer be thrown if the value of a promoted property is unset
  
  The code fix is targeted to be included in the maintenance
  delivery vehicle following 8.5.0.1.
  

Temporary fix
