Watch your transitive dependencies. By using information from the question and mvn dependency:tree, this is what I get:

+- org.springframework:spring-context:jar:4.0.3.RELEASE:compile
|  +- org.springframework:spring-aop:jar:4.0.3.RELEASE:compile
|  +- org.springframework:spring-beans:jar:4.0.3.RELEASE:compile

You can see that the older versions of Spring WS and Spring Security pulled some old Spring Framework dependencies as well. I strongly suggest to add <dependencyManagement> section to your POM and force those dependencies to be 4.0.3:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web/artifactId>
            <version>4.0.3.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-oxm</artifactId>
            <version>4.0.3.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>4.0.3.RELEASE</version>
        </dependency>
    </dependencies>
</dependencyManagement>
