#  The test verifies that crashed in the middle of XA COMMIT server
#  does not lose the prepared transaction, neither it gets committed.
#  This is to test that fixes to  BUG #12161 Xa recovery and client disconnection
#  do not break existing policy.
#  The prepared XA can be identified and concluded with XA COMMIT or ROLLBACK,
#  "manually" by the user.
