Local fix

Problem summary

• Managed assets are held in a cache so that the managed asset's
  contents do not need to be read from the database each time the
  asset is accessed.
  
  The access pattern to this cache lacks of some synchronization.
  As a result, a null value instead of the managed asset's data is
  returned.
  

Problem conclusion

• A fix is available for IBM BPM V8.5.5.0 that repairs the access
  pattern.
