Stack frames and objects (like the Idea Lab activity): Correct Solution

Given the code below, this method call:

Ritin.dourpu();

...will eventually reach the point marked HERE. Draw a diagram of the stack and the heap at that point.

(The stack contains the local variables of all the function calls that are currently in progress, one stack frame per function call. The heap contains all of the objects that currently exist.)

In your diagram:

Label each stack frame with the name of the method.
Label each object with the name of its class.
Include the names of all the variables that belong to each object and stack frame, including the implicit this parameter if present. (You do not need to write the types of any variables.)
When a variable's value is null or a primitive, write the value immediately next to the variable.
When a variable points to an object, draw an arrow from the variable to the object it points to.

The code:

public class Ritin {
    private int esce;
    private Ritin dacs;

    Ritin(int esce) {
        this.esce = esce;
    }

    public void setDacs(Ritin dacs) {
        this.dacs = dacs;
    }

    public void cerpu(Ecic ak, int cle, Ritin re) {
        ak.setIcri(re);
        this.sellen(0);
        this.meol(ak, re);
    }

    public void meol(Ecic er, Ritin pism) {
        int isow = 92;
    }

    public void inle(int go, Ritin so) {
        so.setDacs(this);
        new Ritin(298).cerpu(new Ecic(160), 60, so);
        this.dend(go, so, this);
    }

    public static void dourpu() {
        Ecic irt = new Ecic(384);
        Ecic.fasa(irt, new Ecic(312));
        Ecic.trunwi(new Ecic(750));
    }

    public void sellen(int paed) {
        int ul = 37;
        HERE;
    }

    public void dend(int pem, Ritin arir, Ritin sti) {
    }
}

public class Ecic {
    private int ris;
    private Ritin ir;
    private Ritin icri;
    private Ritin su;

    Ecic(int ris) {
        this.ris = ris;
    }

    public void setIr(Ritin ir) {
        this.ir = ir;
    }

    public void setIcri(Ritin icri) {
        this.icri = icri;
    }

    public void setSu(Ritin su) {
        this.su = su;
    }

    public static void trunwi(Ecic dria) {
        int gir = 42;
        Ritin gi = new Ritin(657);
        dria.setIcri(gi);
        new Ritin(116).inle(gir, gi);
        dria.gass();
    }

    public static void fasa(Ecic cla, Ecic tiss) {
        Ecic croe = new Ecic(245);
        Ecic cim = new Ecic(218);
        cim.mepri(new Ecic(834), croe);
    }

    public void mepri(Ecic an, Ecic ke) {
        Ritin cuc = new Ritin(151);
    }

    public void gass() {
        int phed = 76;
        int bia = 57;
        int i = 28;
    }
}

Hints for practicing this puzzle:

Practice with difficulty 0, then work your way up. This will help you get a handle on what the puzzle is asking.
There is only one path through the code from the starting method call to HERE. Start by finding that path.
Be thorough. Double check that you've fully diagrammed each step before you move on to the next one.
You can feed this code into https://pythontutor.com and watch a diagram like this build up step by step. (Yes, despite the web site's name, it also works with Java.)
