JR44619: CAPITAL LETTERS IN USERNAME WHEN HUMAN TASK IS ALLOCATED TO LIST PRODUCES NULLPOINTEREXCEPTION (NPE)

Version 8.0.1 Fix Pack 1 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• Capital letters in username when human task is allocated to
  list of users produces a NullPointerException (NPE)
  .
  Problem description
  Steps to reproduce:
  1. Import TWX attached to this PMR
  2. Create user with username "test1" - be careful, DO NOT
  capitalize
  any letter in username while creating this user in internal BPM
  user
  repository 3. Start "ListOfUsersTest" BPD
  
  It produces Null Pointer Exception without starting BPD.
  
  Steps which will fix NPE:
  1. Change "Init list" script, and decapitalize first letter of
  username like:
   tw.local.listOfUsers.insertIntoList(0, "test1");
  2. Start "ListOfUsersTest" BPD
  
  It is normally startable now
  
  Another check:
  1. Change "Init list" script, and write in non-existing
  username, like:
   tw.local.listOfUsers.insertIntoList(0, "dummyUser");
  2. Start "ListOfUsersTest" BPD
  
  Error message is understandable now, saying that user doesn't
  exist.
  
  Another check:
  1. Create user "test2" in BPM internal user repository 2. Change
  "Init list" script, by putting 2 users in list, like:
   tw.local.listOfUsers.insertIntoList(0, "test1");
   tw.local.listOfUsers.insertIntoList(1, "Test2"); 2. Start
  "ListOfUsersTest" BPD
  
  Which doesn't produce previously reported NPE.
