hi @tillrohrmann there is a little difference between `RandomUtils.nextLong
` and `ThreadLocalRandom.current().nextLong` , that is the former allows
**startInclusive = endExclusive** but the latter does not allow. However, in
CheckpointCoordinator exists :
```
if (baseInterval < minPauseBetweenCheckpoints) {
baseInterval = minPauseBetweenCheckpoints;
}
```
so Travis-CI test failed. ---
