```suggestion
final Set<CoLocationGroupDesc> coLocationGroupDescs = new
HashSet<>();
for (JobVertex vertex : getVertices()) {
CoLocationGroup coLocationGroup =
vertex.getCoLocationGroup();
if (coLocationGroup != null) {
CoLocationGroupDesc coLocationGroupDesc =
CoLocationGroupDesc.from(coLocationGroup)
coLocationGroupDescs.add(coLocationGroupDesc);
}
}
```
