    Steps to Reproduce: 
Minimal example to reproduce the issue:

Failing expression: #{simpleOrderHandler.getLastUpdate(null)}
{code:java}

    import java.util.Date;  
      
    public interface SimpleDataTableHandler<T> {  
     public Date getLastUpdate(T item);  
    }  
      
    import java.util.Date;  
    import javax.enterprise.inject.Model;  
      
    @Model  
    public class SimpleOrderHandler implements SimpleDataTableHandler<SimpleOrder> {  
      
        @Override  
        public Date getLastUpdate(SimpleOrder item) {  
            return new Date();  
        }
