Review comment:
something like this? I can give it a try. But it basically boils down to
single thread case anyway.
```
_executorServiceConnection.scheduleAtFixedRate(() -> {
// Randomly pick a Participant and cause a transient connection issue
synchronized (_executorServiceConnection) {
int participantIndex = RANDOM.nextInt(_numNodes);
stopParticipant(participantIndex);
startParticipant(participantIndex);
}
}, 0L, CONNECTION_DELAY, TimeUnit.MILLISECONDS);
```
