Spring AOP creates additional bean

Question

I play with Spring AOP.

Here is a simple class

public class CModel extends Car {
    private double torqueMeasure = 1;

    public CModel() {
        System.out.println(" C-Model constructor");        
    }
}

And Spring configuration is like this

<aop:config>
    <aop:aspect ref="audit">
        <aop:before pointcut="execution(* com.test.main..*(..))" method="firstControl"/>
            ...
    </aop:aspect>
</aop:config>

It's good now; when I add aop: config and intercept the CModel, then Spring calls the CModel constructor twice. This means that Spring creates 2 CModel objects, right?

If I remove the AOP configuration, then Spring will only create one CModel object.

Any idea why this is?

Thank.
