XA transaction failure with 3 involved servers

Issue

• Setup/ call sequence:
  • client invokes EJB A on server A,
  • on server A
    • Container on A starts tx,
    • EJB A updates record in database and
    • invokes remotely EJB B on server B
  • on server B
    • EJB B again invokes a datasource and
    • invokes EJB C on server C,
  • on server C
    • EJB C updates record in database.
• During invocation/transaction in flight server B crashes and get restarted
• as some tx-branches get committed while other get rolled-back the outcome is inconsistent.
