IT17337: USING MBXPATH TO PROCESS MANY REPEATING RECORDS CAN LEAD TO INTEGRATION SERVER TERMINATION DUE TO STACK OVERFLOW

APAR status

• Closed as program error.

Error description

• If the MbXPath object from the Java Plugin Node API  is used to
  reference or update a message using XPath expressions, it may
  cause the entire message to be parsed. If the message contains
  many repeating structures then this can cause the integration
  server (execution group) to terminate, due to a stack overflow
  and as such an abend file may not be written.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus v10.0 using the MbXPath object
  from the Java Plugin Node API to parse an XML message that
  contains many repeating structures.
  
  
  Platforms affected:
  z/OS, MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The Java Plugin Node API has an MbXPath object which can be used
  to reference or update a XML message using XPath expressions.
  
  If the message contains many repeating structures and the XPath
  expressions cause all parts of a message to be parsed, this can
  cause the integration server (execution group) to terminate due
  to a stack overflow and as such an abend file may not be
  written.
  

Problem conclusion

• Irrespective of how many repeating structures are parsed by an
  MbXPath object, the integration server will no longer terminate.
