SpringAOP中Advice的织入和执行问题

Question

Bean类：

package aop.schema.advice.biz;

public class AspectBiz {
    
    public void biz() {
        System.out.println("AspectBiz biz.");
        throw new RuntimeException();
    }
}

Aspect类：

package aop.schema.advice;

import org.aspectj.lang.ProceedingJoinPoint;

public class MoocAspect {
    
    public void before() {
        System.out.println("MoocAspect before.");
    }
    
    public void afterReturning() {
        System.out.println("MoocAspect afterReturning.");
    }

    public void afterThrowing() {
        System.out.println("MoocAspect afterThrowing.");
    }

    public void after() {
        System.out.println("MoocAspect after.");
    }
    
    public Object around(ProceedingJoinPoint pjp) {
        Object obj = null;
        try {
            System.out.println("MoocAspect around 1.");
            obj = pjp.proceed();
            System.out.println("MoocAspect around 2.");
        } catch (Throwable e) {
//            e.printStackTrace();
        }
        return obj;
    }
}

配置文件：

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

    <bean id="moocAspect" class="aop.schema.advice.MoocAspect"></bean>

    <bean id="aspectBiz" class="aop.schema.advice.biz.AspectBiz"></bean>
    <bean id="myBiz" class="aop.schema.advice.biz.MyBiz"></bean>

    <aop:config>
        <aop:aspect id="moocAspectAOP" ref="moocAspect">
            <aop:pointcut id="moocPointcut" expression="execution(* aop.schema.advice.biz.*Biz.*(..))"/>
            <aop:before method="before" pointcut-ref="moocPointcut"/>
            <aop:after-returning method="afterReturning" pointcut-ref="moocPointcut"/>
            <aop:after-throwing method="afterThrowing" pointcut-ref="moocPointcut"/>
            <aop:after method="after" pointcut-ref="moocPointcut"/>
            <aop:around method="around" pointcut-ref="moocPointcut"/>
        </aop:aspect>
    </aop:config>

</beans>

测试类：

package aop;

import aop.schema.advice.Fit;
import aop.schema.advice.biz.AspectBiz;
import base.UnitTestBase;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.BlockJUnit4ClassRunner;

@RunWith(BlockJUnit4ClassRunner.class)
public class TestAOPSchemaAdvice extends UnitTestBase {
    
    public TestAOPSchemaAdvice() {
        super("classpath:spring-aop-schema-advice.xml");
    }
    
    @Test
    public void testBiz() {
        AspectBiz biz = super.getBean("aspectBiz");
        biz.biz();
    }
}

现在的问题是：
按理说AspectBiz在执行biz()时抛出异常，afterThrowing()应该执行，然而当5个advice全开时testBiz()的执行结果是：

MoocAspect before.
MoocAspect around 1.
AspectBiz biz.
MoocAspect after.
MoocAspect afterReturning.

结果显示afterThrowing()并没有执行，执行的是afterReturning()。
更神奇的是，如果我注释掉before这个advice，再次运行testBiz()的结果是：

MoocAspect around 1.
AspectBiz biz.
MoocAspect afterThrowing.
MoocAspect after.

这下正常了。
为什么会这样呢？为什么before advice会影响到after-throwing advice的执行呢？
和SpringAOP对advice的织入方式有关吗？那么SpringAOP的织入方式又是什么样的呢？
