Review comment:
I'd extract a method here:
```
this.executionVertexIDComparator = new
ExecutionVertexIDComparator(getSortedJobVertices());
...
private static List<JobVertexID> getSortedJobVertices(final JobGraph
jobgraph) {
return jobGraph
.getVerticesSortedTopologicallyFromSources()
.stream()
.map(JobVertex::getID)
.collect(Collectors.toList());
}
```
