Review comment:
nit: might be better to place these two lines out of loop to together
with `barrierHandler`
```
CheckpointBarrierHandler barrierHandler =
checkpointedMultipleInputGate[0].getCheckpointBarrierHandler();
assertTrue(barrierHandler.getBufferReceivedListener().isPresent());
BufferReceivedListener bufferReceivedListener =
barrierHandler.getBufferReceivedListener().get();
```
