Has trouble with children of abstract classes

When encountering a child, it creates a duplicate call to the superclass. At the bottom of the following generated code, the first call to super() with no arguments is incorrect. The second one, with five null arguments, is the correct call.

In addition, in the ObjectFactory, it does not call the right constructor for some classes that pass arguments to a superclass:

ObjectFactory factory method that has error:

``` java
/**
* Create an instance of {@link SphereVolumeRef }
*
*/
public SphereVolumeRef createSphereVolumeRef() {
return new SphereVolumeRef();
}
```

Should be:

``` java
/**
* Create an instance of {@link SphereVolumeRef }
*
*/
public SphereVolumeRef createSphereVolumeRef() {
return new SphereVolumeRef(null);
}
```

Your code is great, and these are easy errors to fix manually. However, I have a project with hundreds of auto-generated classes. This poses an issue.
