workflow.18002.delta.repository

APAR status

• Closed as program error.

Error description

• The Move token REST API fails with a NullPointerException if you
  try to move the same token more than once. For example, you see
   the NullPointerException when a token is moved from an activity
   to a decision gateway and then sent back by the gateway to the
  same activity it was originally moved from.
  
  You also see a stack trace in the server log file:
  
  CWLLG2229E: An exception occurred in an EJB call.  Error:
