As Willem stated, this is working as designed. If you only need a Client object and not a proxy, you should likely use the JaxWsClientFactoryBean and not any of the various ways that a proxy is created (service object, JaxWsProxyFactoryBean, etc…).
Basically, if you create a proxy, that proxy is the "root" of everything related to it and needs to be help onto strongly for as long as anything internal to it is being used.
