GWT Autobean List for different objects

Question

In addon my question question

My JSON

{
    "status" : "SUCCESS",
    "count" : 1,
    "type" : "InfraNameModel",
    "results" : [{
            "infraName" : "TEST1"
        }
    ]
}

IBeanFactory

public interface IBeanFactory extends AutoBeanFactory {
    IBeanFactory INSTANCE = GWT.create(IBeanFactory.class);
    AutoBean<InfraNameModel> infraName();
    AutoBean<InfraNameListModel> results();
}

InfraNameListModel

public interface InfraNameListModel {
    List<InfraNameModel> getResults();    
    void setResults(List<InfraNameModel> infraNameModel);
}

InfraNameListModelImpl

public class InfraNameListModelImpl implements InfraNameListModel {  
    private List<InfraNameModel> results;    
    @Override
    public List<InfraNameModel> getResults() {
        return results;
    }

    @Override
    public void setResults(List<InfraNameModel> results) {
        this.results = results;
    }
}

InfraNameModel

public interface InfraNameModel {
    String getInfraName();   
    void setInfraName(String infraName);
}

InfraNameModelImpl

public class InfraNameModelImpl implements InfraNameModel {
    private String infraName;
    @Override
    public String getInfraName() {
        return infraName;
    }
    @Override
    public void setInfraName(String infraName) {
        this.infraName = infraName;
    }
}

How I use

            InfraNameListModel infraNameListModel = beanFactory.deserializeFromJson(jsonParser.getResultsJSON());
            logger.info(infraNameListModel.toString());
            List<InfraNameModel> infraNameModelList = infraNameListModel. getResults();
            logger.info(infraNameModelList.toString());
            InfraNameModel infraNameModelImpl = infraNameModelList.get(0);
            logger.info(infraNameModelImpl.toString());

All work fine. But I have a questuion.

In the "Results" can come different types of beans.How to make a generic List for all types?

I try so

public interface ResultsModel<T> {
    List<T> getResults();
    void setResults(List<T> infraNameModel);
}

InfraNameResultsModelImpl

public class InfraNameResultsModelImpl implements ResultsModel<InfraNameModel> {
    private List<InfraNameModel> results;
    @Override
    public List getResults() {
        return results;
    }
    @Override
    public void setResults(List infraNameModel) {
        this.results = results;
    }
}

But error = (

Is it possible to implement a common List for all types of results?

            ResultsModel<InfraNameModel> resultsModel = beanFactory.deserializeFromJson(ResultsModel.class,jsonParser.getResultsJSON());
            logger.info(resultsModel.toString());
            List<InfraNameModel> infraNameModelList = resultsModel. getResults();
            logger.info(infraNameModelList.toString());
            InfraNameModel infraNameModelImpl = infraNameModelList.get(0);
            logger.info(infraNameModelImpl.toString());
