The introduced filed it inserted before other filed declaration, although it can have reference to it. 

Steps to reproduce: 
1) introduce field from "d+x" in following code and select "initialize in field"

public class ClassA {
    
    int d = 3;
    
    int x = 3;
           
    public void neco() {
        System.out.println(d + x);
    }
}


Result (invalid forward reference):
public class ClassA {
    public int name = d + x;
    
    int d = 3;
    
    int x = 3;
           
    public void neco() {
        System.out.println(name);
    }
}
