  * PROBLEM DESCRIPTION: A NullPointerException occurs when      *
  *                      searching for a non-existent user       *
  *                      using REST API.                         *

  ****************************************************************
  Process Portal utilizes REST API  to modify task details
  during runtime. Users can utilize the  ¢â‚¬ “Modify Task ¢â‚¬  ½
  in Process Portal to reassign tasks to other users. If a
  string which does not match any existing user names is passed,
  a NullPointerException occurs.
  The following REST API HTTP request URL may be seen when
  invoking the task assignment function:
   ¢â‚¬ “/rest/bpm/wle/v1/users?filter=*an*&maxresult=11&assignTas
  il
  ter=3819&namesonly=true&parts=none ¢â‚¬  ½
  As a result a 500 error code is returned by REST API and the
  reassignment invocation is interrupted. The 500 error code may
  be seen in logs or any web browser debug plugin, however, on
  the browser screen it will only show the message  ¢â‚¬ “Unexpect
  error occurred ¢â‚¬  ½.
  The following exception stack may be seen in the trace logs:
  RestHelper    W   <Null Message>
  java.lang.NullPointerException

Problem conclusion

• The user look-up functionality in REST API has been corrected
  to handle non-existent user names properly. A fix for 8.0.1.1
