java.lang.IncompatibleClassChangeError with Struts2 and spring integration

Question

i'm trying to integrate Spring 4.0.6 in a struts 2.3.1.2 application. This is the maven POM:

</project>

this is the relevant portion of struts.xml:

<constant name="struts.objectFactory.spring.autoWire" value="type" />
    <constant name="struts.objectFactory" value="spring" />

and finally this is the spring applicationContext.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"

        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

    <context:annotation-config/>
</beans>

i'm trying to configure the service layer with Spring annotation but i'm stuck on this startup exception:
