Local fix

  • 



Problem summary


    

  • The Artifact Loader has some caches for artifact loading. One of
 the caches is not synchronized and, therefore, might be
inaccessible when the concurrent volume is high.

PRODUCTS AFFECTED

Problem conclusion


    

  • A fix to prevent the concurrency issue will be included in IBM
BPM V8.5.7 cumulative fix 2017.06.
