PI98038: IMPROVE DFHJS2LS SERVICEABILITY FOR RECURSION LOOP RESULTING IN OUTOFMEMORY ERROR JVMDUMP013I

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You are using DFHJS2LS to process a document with recursive
  definitions.  Recursion is not supported by DFHJS2LS, however
  the code should not loop processing the recursion elements
  until Java OutOfMemory occurs, but detect the unsupported
  recursion and throw an exception.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: DFHJS2LS terminates due to an           *
  *                      OutOfMemoryError.                       *
  ****************************************************************
  DFHJS2LS is run in preparation for creating a JSON web service
  or program that converts JSON to/from application data.  A JSON
  schema was provided as input which contains a recursive JSON
  pointer ($ref).  This causes DFHJS2LS to loop until an
  OutOfMemoryError occurs.
  

Problem conclusion

• DFHJS2LS has been updated to exit with message DFHPI9740E if a
  JSON schema is input which contains a recursive pointer, as
  recursive JSON schema are not supported.
  
  The CICS Transaction Server for z/OS 5.4 and 5.5 Knowledge
  Centers will be updated to add new message DFHPI9740E.
  
  DFHPI9740E Unsupported JSON schema. A recursive JSON pointer
  \"pointer\" was found.
  
  Explanation
  
  A JSON pointer was encountered within a schema that would result
  in a recursive structure.  Recursive pointers are not supported.
  
  System Action
  
  The assistant ends.
  
  User Response
  
  Remove the unsupported pointer.
