Supposing a value class with itself as a field.
value class Node {
     Node node;
}

var n1 = new Node(null);
var n2 = new Node(n1);

n1 == n2;

Results in StackOverFlowError trying to create/find a methodHandle to perform `equals`.

If embedding were intended, this would be clearly illegal and should result in a compile time error; but in this case the field is a reference to a Node.
