Local fix

  • 



Problem summary


    

  • IBM BPM does not support recursive business object values, which
is what occurs when the complex value of a business object
contains itself.
If a variable of a BPD instance contains a recursive value, a
java.lang.StackOverflowError is thrown, and the BPD instance
goes into the FAILED state.

    



Problem conclusion


    

  • A fix is available for IBM BPM V8.5.7 cumulative fix 2016.06
on request from level 3 support that recognizes recursive values
and handles them correctly.

A fix is included in IBM BPM V8.5.7 cumulative fix 2016.12
