modelmapper: ModelMapper: Does not map nested collections of List

I have similar example like below:

public class FirstObject {
    private List<SecondObject> myListOne;
    ...only getter method...
    ...no setter method for the list due to it is generated from wsdl 
}
public class SecondObject {
    private List<ThirdObject> myListTwo;
    ...only getter method...
    ...no setter method for the list due to it is generated from wsdl
}
public class ThirdObject {
    private String firstName;
    private String lastName;
    ...setters and getters...
}

FirstObject rq = new FirstObject();
...fills some data...

ModelMapper modelMapper = new ModelMapper();
FirstObjectDTO = modelMapper.map(rq, FirstObjectDTO.class);

The main issue are setter methods for the lists. If you try with PropertyMap or even with Providers you have to use setter methods and I cannot make them manually because all objects will be regenerated from wsdl each time when I run mvn eclipse:eclipse command.

In case that we have setter methods everything will work properly.

Is there any solution how to make this with Converter??
