Local fix

Problem summary

• Invalid sessions are not correctly handled in Business Process
  Choreographer Explorer when you resume work in the web-based

  inactivity has passed. As a result, you receive a
  NullPointerException.
  

Problem conclusion

• A fix is available for IBM BPM V8.5.0.1 that improves how
