  The problem is fixed with this APAR.  This APAR introduces an
  option for customer to persist the results of the XSLT
  transformation to disk by setting 2 environment variables:
  ENABLE_SERIALIZED_COACH=true
  SERIALIZED_COACHES_FOLDER=c:\temp\persistedCoaches (or
  whatever folder you choose)
  These options are more suitable to a production or staging
  environment, since within these types of environments the
  number of coaches will be limited to the number of snapshots
  of a process application deployed to these servers. Applying
  this in a development environment could result in a large
  number of temporary files. Each playback done for a newly
  changed coach could result in a new cache file.
  FIX AVAILABILITY:
  The fix is planned to be available in the future releases of
  BPM 8.0.1 and 8.5.0.
