  create a user task, in combination with 'optimize execution for
  latency' for the business process definition (BPD), you will see
  the following TeamWorksException in SystemOut.log:

Local fix

Problem summary

• The 'optimize execution for latency' feature introduces a new
  infrastructure that must be initialized on each thread that uses
  it. The 'automatically flow to next task' feature uses a special
  thread on which the 'optimize execution for latency'
  infrastructure is not initialized.
  

Problem conclusion

• A fix is available for IBM BPM 8.5.5.0 that initializes the
  'optimize execution for latency' infrastructure on the
  'automatically flow to next task' thread. With this fix, using
  both features in combination allows an automatic flow to the
  next user task even if a system task or a decision task is
  between the current user task and the next user task.
