在调用外部供应商 Web 服务时，我正在模拟超时异常（或任何其他异常）。我在流程开始时存储原始有效负载，并在捕获异常策略中，将有效负载替换为原始有效负载。有效负载被替换得很好，应用 XSLT 转换器很好，将转换后的有效负载复制到文件出站很好，但奇怪的是 JMS 得到空消息（尽管消息属性是完整的）。使用Mule 3.3.1和ActiveMQ。如果 Active MQ 替换为Sonic

<flow name="orderRequirementsToVendor">
        <jms:inbound-endpoint queue="order.vendor" />
        <set-variable variableName="originalPayload" value="#[message.payload]" />
        <outbound-endpoint address="${vendor.ws.url}" mimeType="text/xml" connector-ref="https.connector" responseTimeout="100">
            <cxf:proxy-client payload="body" enableMuleSoapHeaders="false">
                <cxf:inInterceptors>
                    <spring:bean class="org.apache.cxf.interceptor.LoggingInInterceptor" />
                </cxf:inInterceptors>
                <cxf:outInterceptors>
                    <spring:bean class="org.apache.cxf.interceptor.LoggingOutInterceptor" />
                </cxf:outInterceptors>
            </cxf:proxy-client>
        </outbound-endpoint>
        .
            .
            .

        <choice-exception-strategy>
            <catch-exception-strategy>
                <logger message="In catch exception strategy. Unknown Exception" level="ERROR" /> 
                <logger message="#[exception.causeException]" level="ERROR" />
                <set-payload value="#[flowVars.originalPayload]"/>
                <set-property propertyName="exception" value="#[exception.summaryMessage]"/>                
                <transformer ref="generalErrorTransformer" />   
                <file:outbound-endpoint path="/outbound/vendor/error/ack-before" outputPattern="out_vendor_transformed_ack_error_beforeStatusQueue[function:dateStamp].xml" />
                <jms:outbound-endpoint queue="order.status" /> 
                <file:outbound-endpoint path="/outbound/vendor/error/ack-after" outputPattern="out_vendor_transformed_ack_error_afterStatusQueue[function:dateStamp].xml" />                    
            </catch-exception-strategy>
        </choice-exception-strategy>        
    </flow>

两者都ack-before包含ack-after正确有效负载的文件，但在 order.status 中收到的消息为空

编辑： 这是我的日志中的例外
