APAR status

• Closed as program error.

Error description

• The XAFlowBackControl has been re-worked so that it works
  correctly on Liberty.
  
  The facility is to be used in a test environment and should
  only be enabled under the guidance of L3 Service. The
  facility can be used to analyse and test XA Flows between
  the Liberty Tran Manager and Resource Managers but should
  only be used in specific circumstances as advised by L3. It
  is enabled by setting a custom property,
  
  com.ibm.ws.Transaction.fvt=true.
  
  But to use it, the customer needs to provide a user feature.
  Hence the L3 guidance.
