Problem summary

• Complex nested business objects failed to resolve in some cases.
  
  USER AFFECTED:
  Business Process Manager Advanced, Standard and Express.
  
  PROBLEM DETAILED DESCRIPTION:
  The Coach framework has always supported recursive data
  structures - however; in this case, the nested structures were
  in a form that the resolution algorithm was failing. The key
  scenario was multiple recursive structures, under different
  paths of the same Business Object. These paths were being
  processed in parallel, using the same cache objects, and hence
  were overlapping and intefering with each other.
  

Problem conclusion

• The issue has been fixed in all releases beyond and including
  8.0.1. The code change essentially involved retaining cached
  data until such time it could be garbage collected, instead of
  diligently cleaning up. The algorithm was attempting to always
  clean up after itself when resolving items, however, this
  cleanup (removal of items from the cache) caused a parallel
  resolution to run infinitely.
