bpm.8570.cf2017.03.delta.repository
Downloading IBM Business Process Manager V8.5.7 Cumulative Fix 2017.03

APAR status

• Closed as program error.

Error description

• When user tasks of a process are implemented by a human service,
  you might start the human service for the same task more than
  once in multiple browser windows or browser tabs.
  For example, you might click the link of an email notification
  from IBM Business Process Manager (BPM) more than once.
  If a different user owns the task, you might not see the
  expected error message
    ("The task you tried to start is owned by another user.")
  but a generic error message instead ("Ask the administrator to
  check the SystemOut.log file for more information to resolve the
  error.").

Problem summary

• When you run a task, instance information of this service is
  stored in your HTTP session on the server. When the runtime
  environment notices that you do not own the task, it removes the
  information from the HTTP session and displays the "The task
  you tried to start is owned by another user." error.
  If you try to run the same task twice, two concurrent threads
  on the server work with the same HTTP session, which can lead
  to information being removed from the session by one thread
  that the other thread still expected. An unexpected failure
  happens that leads to the generic error message.
  

Problem conclusion

• A fix will be included in IBM BPM V8.5.7 cumulative fix 2017.03
  that ensures that synchronizes concurrent threads for the same
  task instance so that no unexpected failure happens and the
  correct error message is shown.
