JR51880: INACURRATE WARNING APPEARS WHEN MIGRATING INSTANCES: "DETECTED A FLOWOBJECTS LOOP OF LENGTH=XXXX"

8.5.5.0-WS-BPM-IFJR51880
Version 8.5 Refresh Pack 6 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• ERROR DESCRIPTION -
  Migrating process instances that contain unwired subprocesses or
  linked processes that are not ad hoc might  return an inaccurate
  warning message in the SysOut.log file: ?detected a flowobjects
  loop of length=xxxx". Additionally, you might notice performance
  degradation.

Problem summary

• When instance are being migrated, you might see a similar
  warning message appear in the SysOut.log file:
  
  [11/21/14 11:20:46:392 UTC] 000001d9 wle_migration W
  com.lombardisoftware.bpd.runtime.
  engine.cases.MigrateBPDAdhocActivityInstances
  addAdhocActivitiesFromDiagram
  Detected a Flowobjects Loop of length=1020.
  
  or
  
  [2/23/15 12:05:52:478 CST] 00018147 wle_migration W
  com.lombardisoftware.bpd.runtime.
  engine.cases.MigrateBPDAdhocActivityInstances
  addAdhocActivitiesFromDiagram Detected a Flowobjects Loop of
  length=1. FlowObject Id's in this Loop
  are=[BPDObjectIdImpl(...)] .   Current FlowObject is =...,
  id=BPDObjectIdImpl(...) . Stopping the precondition cache
  computation for this loop.
  
  This warning is emitted when processes are self-referential or
  recursive, meaning that a linked process points to the current
  process definition. However, for unwired subprocesses and linked
  processes that do not have ad hoc activity support enabled (?The
  activity runs even though it does not have an inbound flow? is
  set to false), the activity cannot produce ad hoc activity
  instances, so updating the precondition cache is unnecessary and
  detrimental from a performance perspective.
  

Problem conclusion

• A fix is available for IBM BPM V8.5.5.0 that excludes unwired
  non-ad hoc event subprocesses, subprocesses, and linked
  processes when updating the precondition cache during instance
  migration.
