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

Given the code below, this method call:

Ost.pteni();

...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 Ost {
    private int ostil;
    private Ses eeng;
    private Ses pesi;

    Ost(int ostil) {
        this.ostil = ostil;
    }

    public void setEeng(Ses eeng) {
        this.eeng = eeng;
    }

    public void setPesi(Ses pesi) {
        this.pesi = pesi;
    }

    public static void noso() {
        Ses panx = new Ses(810);
        int mipo = 94;
        Ost beua = new Ost(392);
        int xiis = 86;
        int sut = 51;
        beua.setPesi(panx);
        panx.knegod();
    }

    public static void pteni() {
        Ses sio = new Ses(48);
        Ost irm = new Ost(808);
        Ses husa = new Ses(688);
        Ses aa = new Ses(112);
        aa.ladasm(irm, new Ost(251));
        husa.setSiu(aa);
        Ost.noso();
    }

    public void engplu(Ost eul, Ost lii) {
        Ost em = new Ost(559);
    }

    public static void snec() {
        int er = 64;
        int uhet = 69;
        int duss = 60;
    }
}

public class Ses {
    private int ikSte;
    private Ses siu;
    private Ost ple;

    Ses(int ikSte) {
        this.ikSte = ikSte;
    }

    public void setSiu(Ses siu) {
        this.siu = siu;
    }

    public void setPle(Ost ple) {
        this.ple = ple;
    }

    public static void cicSoni(Ses deca) {
        int ceea = 35;
        Ost.snec();
        deca.setSiu(deca);
        Ses.esclue(deca);
    }

    public void ladasm(Ost rher, Ost ekne) {
        new Ost(301).engplu(ekne, new Ost(517));
    }

    public void friPrast(Ses thef, Ses vam, Ses thit) {
    }

    public void knegod() {
        int nin = 54;
        int ta = 14;
        Ses.cicSoni(this);
    }

    public static void esclue(Ses al) {
        Ses.diclim(al, al, al);
        HERE;
        al.friPrast(al, al, al);
    }

    public static void diclim(Ses apal, Ses meod, Ses maiu) {
        int gom = 81;
    }
}

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.)
