Re: [jdt-dev] Non-deterministic binding found

Hi Munawar,

I believe best way to report bugs for JDT is to create ticket at https://github.com/eclipse-jdt/eclipse.jdt.core/issues.

If you are unsure whether it is a bug or not, pleease start discussion here: https://github.com/eclipse-jdt/eclipse.jdt.core/discussions

For the following code,

import java.util.ArrayList;


public class MultiClassWithOverloadedMethods {
    public static void main(String[] args) {
        A x = new A();
        int i = 10;
        while(i>0) {
            x = x.foo(new B());
            i--;
        }
        AnotherClass an = new AnotherClass();
        an.foo();
    }
}

class AnotherClass {
   
    public AnotherClass() {
       
    }
   
    public void anotherFoo() {
        A b = new B();
        A d = b.foo(new D());
    }
   
    public int foo() {
        int haha = 1;
        A x = new D();
        x.foo(new C());
        return haha;
    }
}

class A {
    A foo(A x) {
        return x;
    }
}

class B extends A {
    A foo(A x) {
        return new D();
    }
}

class D extends A {
    A foo(A x) {
        A b = new B();
        b.foo(x);
        return new A();
    }
   
    A foo(A x, ArrayList<A> y) {
        return x;
    }
}

class C extends A {
   
    A foo(A x) {
        D y = new D();
        y.foo(x);
        return this;
    }
}

For the _expression_ 

b.foo(new D())

we get the following binding in some cases

(id=NoId)
class A
extends java.lang.Object
/*   methods   */
[unresolved] non-sealed void <init>()

and we get this in some other cases.

[MISSING:A]

Here is the code I am using.

IBinding nodeBinding = node.resolveBinding();
where node is a SimpleName. Then checking that the IBinding is of IVariableBinding and then doing ths

ITypeBinding typeBinding = ((IVariableBinding)nodeBinding).getType();

How can the result be made consistent? Note, I have to run my code on the Eclipse IDE (With build ID: 20250905-1456) using the debug mode to get the variation. While using eclipse in a normal run, I am always getting the second missing binding.

Thoughts? 

Thanks.
