[Bug]: If there is no parent class source code, invocation.getExecutable() will incorrectly locate other method in this class

[Scrates1]

Describe the bug

When I use Spoon analysis, if there is no parent class source code, invocation.getExecutable() will incorrectly locate other method in this class.

Source code you are trying to analyze/transform

public abstract class A extends Father {
    @Override
    public void add(double x) {
        add(x, 1);
    }

    abstract void add(double x, int w, int base);
}
