AspectJ Pointcut Expression and ProxyFactoryBean(s) with Spring 2.0.1

[awurzer]

Hello,

I've tried to upgrade a Spring 2.0.0 project to Spring 2.0.1. One problem occured with some of my ProxyFactoryBeans which should be intercepted by one of my AspectJPointcutExpressions.
My Aspect intercepts a method of a proxied interface on the target bean of the ProxyFactoryBean.

I've created the following code for reproducing the problem.

Base Interface:

public interface MyService {

	public void someServiceMethod();

	public void someOtherServiceMethod();

	public String getMethodCalledMessage();

	public void setMethodCalledMessage(String method);
}

Proxied Interface:

public interface MyServiceToIntroduce extends MyService {

	public void introducedMethod();
}

Implementation (Target Bean):

public class MyServiceImpl implements MyService {

	private static final Logger logger = Logger.getLogger(MyServiceImpl.class);

	private String methodCalledMessage;

	public void someOtherServiceMethod() {

		logger.info("in someOtherServiceMethod");
		this.setMethodCalledMessage("someOtherServiceMethod");
	}

	public void someServiceMethod() {

		logger.info("in someServiceMethod");
		this.setMethodCalledMessage("someServiceMethod");
	}

	public String getMethodCalledMessage() {
		return this.methodCalledMessage;
	}

	public void setMethodCalledMessage(String method) {
		this.methodCalledMessage = method;
	}

}

Aspect:

@Aspect
public class MyServiceAspect {

	final Logger logger = Logger.getLogger(MyServiceAspect.class);

	@Around(value = "execution(* some.package.MyService*.introduced*(..))"
			+ " && target(service)", argNames = "joinPoint, service")
	public void doIntroduce(ProceedingJoinPoint joinPoint, MyService service) {

		logger.info("in aspect: doIntroduce");
		service.setMethodCalledMessage(joinPoint.getSignature().getName());
	}

}

applicationContext-proxyFactoryBean.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd">

	<aop:aspectj-autoproxy />

	<bean id="myServiceAspect"
		class="some.package.MyServiceAspect" />

	<bean id="myService"
		class="org.springframework.aop.framework.ProxyFactoryBean">
		<property name="proxyInterfaces">
			<value>
				some.package.MyServiceToIntroduce
			</value>
		</property>
		<property name="target" ref="myServiceTarget" />
	</bean>

	<bean id="myServiceTarget"
		class="some.package.MyServiceImpl" />
</beans>

Test:

public class AtAspectJPointcutExpressionWithProxyFactoryBeanInContextTest
		extends AbstractSingleSpringContextTests {

	public void testPointcutExpression() throws Exception {

		MyServiceToIntroduce serviceToIntroduce = (MyServiceToIntroduce) applicationContext
				.getBean("myService");

		serviceToIntroduce.introducedMethod();

		assertEquals("introducedMethod", serviceToIntroduce
				.getMethodCalledMessage());
	}

	@Override
	protected String[] getConfigLocations() {
		return new String[] { "classpath:/applicationContext-proxyFactoryBean.xml" };
	}

}

Stacktrace:

org.springframework.aop.AopInvocationException: AOP configuration seems to be invalid: tried calling method [public abstract void test.at.ccservices.spring.aop.service.MyServiceToIntroduce.introducedMethod()] on target [test.at.ccservices.spring.aop.service.MyServiceImpl@136a43c]; nested exception is java.lang.IllegalArgumentException: object is not an instance of declaring class

With Spring 2.0.0 everything works fine! Thanks for your help in advance!
