IT39213: INPUT BITSTREAM IS NOT REUSED BY THE JSON PARSER IN SOME SITUATIONS WHERE IT COULD BE.

APAR status

• Closed as program error.

Error description

• In order to maximise performance the parsers in IBM Integration
  Bus and App Connect Enterprise will often re-use the input
  bitstream when serialising if it has been detected as valid. In
  the case of the JSON parser when the serialisation encoding is 0
  and the input encoding matches the default encoding the input
  bitstream could be re-used but is not.
  
  
  This may be detectable due to differences in preservation of
  whitespace or escaped characters in the serialised output.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus version 10 or App Connect
  Enterprise version 11 or 12 using the JSON parser.
  
  
  Platforms affected:
  MultiPlatform

  This may be detectable due to differences in preservation of

Problem conclusion

• JSON parser instances are now eligible for re-use when the
  serialisation encoding is 0 and the input encoding matches the
  default encoding.
