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.

    IBM BPM Advanced
    

Problem conclusion

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