Review Comment:
The new code looks like:
```
public void setDistributionManagement(DistributionManagement
distributionManagement) {
if (!Objects.equals(distributionManagement,
getDistributionManagement())){
if (distributionManagement != null) {
update(getDelegate().withDistributionManagement(distributionManagement.getDelegate()));
distributionManagement.childrenTracking = this::replace;
} else {
update(getDelegate().withDistributionManagement(null));
}
}
}
```

Review Comment:
So the new code now looks like:
```
public void setDependencies(List dependencies) {
if (dependencies == null) {
dependencies = Collections.emptyList();
}
if (!Objects.equals(dependencies, getDependencies())) {
update(getDelegate().withDependencies(
dependencies.stream().map(c ->
c.getDelegate()).collect(Collectors.toList(;
dependencies.forEach(e -> e.childrenTracking = this::replace);
}
}
