    ****************************************************************
    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.
