Spring Apache CXF处理程序问题

我面临CXF处理程序的问题（使用CXF 2.7.6版）。在我的xml文件中，定义了多个web服务客户端。我为服务1添加了一个简单的处理程序

<jaxws:client id="service1"
    serviceClass="com.Service1" address="${E1}"
    username="${U1}" password="${P1}">
    <jaxws:features>
        <beans:bean class="org.apache.cxf.feature.LoggingFeature" />
    </jaxws:features>
    <jaxws:handlers>
        <beans:bean class="com.SOAPMessageLoggingHandler" />
    </jaxws:handlers>

</jaxws:client>

<jaxws:client id="service2"
    serviceClass="com.Service2" address="${E2}"
    username="${U2}" password="${P2}">
    <jaxws:features>
        <beans:bean class="org.apache.cxf.feature.LoggingFeature" />
    </jaxws:features>
</jaxws:client>

现在，上述配置将导致

org.apache.cxf.interceptor.Fault:客户端已关闭

当使用第二个服务（服务2）且服务1工作正常时。但以下配置对于这两种服务都可以正常工作

<jaxws:client id="service2"
    serviceClass="com.Service2" address="${E2}"
    username="${U2}" password="${P2}">
    <jaxws:features>
        <beans:bean class="org.apache.cxf.feature.LoggingFeature" />
    </jaxws:features>
</jaxws:client>

<jaxws:client id="service1"
    serviceClass="com.Service1" address="${E1}"
    username="${U1}" password="${P1}">
    <jaxws:features>
        <beans:bean class="org.apache.cxf.feature.LoggingFeature" />
    </jaxws:features>
    <jaxws:handlers>
        <beans:bean class="com.SOAPMessageLoggingHandler" />
    </jaxws:handlers>
</jaxws:client>

为什么订单会引起问题？添加到一个客户端的处理程序会影响另一个客户端吗
