   All tests have been successful
   The functionality of ForwardRecovery has been incorporated into 
defaultRecovery, so delete it and its test code. There is a test code 
equivalent to ForwardRecover in TransactionAspectTest.
   (-1) means infinite retry, but it can also be interrupted, throwing an 
InterruptedException, which is consistent with the logic in the previous 
ForwardRecovery
