workflow.20002.delta.repository

APAR status

• Closed as program error.

Error description

• When there are heavy loads for an Advanced Integration service
  (AIS) that has an SCA binding and you set the business object
  parsing mode as Eager, you could get the following error:
  
  An error occurred while parsing native data: The error message
  is: java.lang.RuntimeException: Error reading XML.

Local fix

Problem summary

• The Eclipse Modeling Framework (EMF) model of the header for AIS
   communication with an SCA binding in the message was not
  pre-initialized when the invocation occurred, possibly leading
  to multiple threads trying to access the EMF model, which EMF
  doesn't support.
  

Problem conclusion

• A fix that pre-initialize the EMF model of the header for AIS
  communication with an SCA binding is available for IBM BPM
  V8.6.0.0 cumulative fix 2018.03.
