PI17548: DFHJSON REUSES CONTAINERS INCORRECTLY

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• JSON2COBOL converter returns randomly wrong CONTAINER content
  to a Cobol application.
  
  This is caused by the fact that program DFHJSON is called for
  the first time and then data from this first call is used as
  input to later calls to DFHJSON. As soon as the second call
  is done the container data is overwritten. (Reuse of the
  DFHPIAXIS-nnnnnn containers)
  

Local fix

• Application to work around this issue would be
  to use a new channel on each call to DFHJSON.

  * USERS AFFECTED: All CICS Users                               *
  ****************************************************************
  * PROBLEM DESCRIPTION: Mulitple calls to DFHJSON using the     *
  *                      same channel cause containers to be     *
  *                      reused.                                 *

  * RECOMMENDATION:                                              *
  ****************************************************************
  An application calls DFHJSON to convert JSON to program data.
  This conversion creates DFHPIAXIS-nnnnnn containers to hold
  parts of the data.  If another call is done to DFHJSON using the
  same channel then the DFHPIAXIS-nnnnnn containers may be reused
  incorrectly and this can cause unpredictable side effects to the
  the application.
  

Problem conclusion

• Update ChannelState.java to set the container counter to 0 or
  obtain the value from the container DFHPIAX-CNT-CONT if it
  exists.
