Different nodes have same hashcode

[Laughh]

Hello! I'm using JP, and in the following code, I found that variables have the same hashCode in different scopes

public void hash(){
    {
        // 1
        Object cnt = new Object();
        cnt.equals(null);
    }
    {
        // 2
        Object cnt = new Object();
        cnt.equals(null);
    }

}

Here is the output. The ranges are different, but the hash code is Identical value. And is there any way to distinguish the two VariableDeclarators by hash code?

cnt = new Object()
Optional[(line 56,col 20)-(line 56,col 37)]
-628174007
--------------------
cnt = new Object()
Optional[(line 61,col 20)-(line 61,col 37)]
-628174007
--------------------

Hi, The hashcode calculation for a variable declaration is based on the name, type, comments and initialisation expression attributes.

But why the range are not considered？

I don't know exactly. It's a functional equality which is obtained by an in-depth check of all the attributes which describe a node.
