Review comment:
Can any one of this work-
```
return Stream.of(nodes1, nodes2).flatMap(Collection::stream).map(n ->
n.getType().getSqlTypeName()).distinct()
.count() == 1;
```
```
return CollectionUtils.union(nodes1, nodes2).stream().map(n ->
n.getType().getSqlTypeName()).distinct().count()
== 1;
```
```
return Stream.concat(nodes1.stream(),nodes2.stream()).map(n->
n.getType().getSqlTypeName()).distinct().count() == 1;
```
