HuZheting opened a new issue #253: when AbortEvent is late
URL: https://github.com/apache/incubator-servicecomb-saga/issues/253
 
 
   I write a test in AlphaIntegrationTest,
   `
     public void whenAbortEventIsLate(){
         
         String sagaGlobalId = UUID.randomUUID().toString();
         String localIdEntry = UUID.randomUUID().toString();
         String localIdEndpoint = UUID.randomUUID().toString();
         
         String anotherSagaGlobalId = UUID.randomUUID().toString();
         String anotheEntryLocalId = UUID.randomUUID().toString();
         String anotherEndPointLocalId = UUID.randomUUID().toString();
         
         asyncStub.onConnected(serviceConfig, compensateResponseObserver);
         blockingStub.onTxEvent(someGrpcEvent(SagaStartedEvent, sagaGlobalId, 
localIdEntry));
         blockingStub.onTxEvent(someGrpcEvent(SagaStartedEvent, 
anotherSagaGlobalId, anotheEntryLocalId));
         
         blockingStub.onTxEvent(someGrpcEvent(TxStartedEvent, sagaGlobalId, 
localIdEndpoint));
         blockingStub.onTxEvent(someGrpcEvent(TxEndedEvent, sagaGlobalId, 
localIdEndpoint));
         await().atMost(1, SECONDS).until(() -> eventRepo.count() == 4);
         
         blockingStub.onTxEvent(someGrpcEvent(TxStartedEvent, 
anotherSagaGlobalId, anotherEndPointLocalId));
         blockingStub.onTxEvent(someGrpcEvent(TxEndedEvent, 
anotherSagaGlobalId, anotherEndPointLocalId));
         blockingStub.onTxEvent(someGrpcEvent(TxAbortedEvent, 
anotherSagaGlobalId, anotherEndPointLocalId));
         
         
         await().atMost(2, SECONDS).until(() -> !receivedCommands.isEmpty());
         assertThat(receivedCommands.poll().getGlobalTxId(), 
is(anotherSagaGlobalId));
         
         blockingStub.onTxEvent(someGrpcEvent(TxAbortedEvent, sagaGlobalId, 
anotheEntryLocalId));
         
         await().atMost(10, SECONDS).until(() -> receivedCommands.size() > 1);
         assertThat(receivedCommands.size(), is(2));
     }`
   and the test fail.

   It seems that the first uncompensate tx  can not be found after another 
abort event is found before.
   I believe that the variable "nextEndedEventId" cause this problem.
